The concept is that bioscopy was quoted as stating was something to the effect of they (those who were in opposition to launching sts-51l the morning of jan 28, 1986) needed to prove to nasa management that a launch wasn't safe, rather than the launch was safe, setting the stage for the tragic loss of crew and vehicle. So Derek try again explaining how you would handle boisjolys situation yourself, if you can, otherwise you public critique of somebody else in that situation really doesn't mean much at all. And since you do not seem to be interested in the facts here is a piece of the diaz report to the Columbia accident investigation board, and please note (in your reading of the rogers commission report) the similarities in describing the communication problems inside nasa, and the creation of the independent technical authority. http://t2www.nasa.r3h.net/pdf/55691main_Diaz_020204.pdf Diaz report to the caib Page 17 "10.1 SUMMARY In summary, the CAIB Report includes significant technical and non-technical R-O-Fs, which NASA leaders must adhere to in order to help the Agency move forward to meet the challenges of the future. The Diaz Team realizes that, in some respects, the most challenging changes will be those which pertain to culture, or those which are the non-technical R-O-Fs noted in the CAIB or Report. The Team knows that the organizational changes recommended in the CAIB Report will require sustained planning implementation over time to achieve the desired future the CAIB and NASA foresee. When making cultural change, large organizations such as NASA need to assure that, throughout the change process the organizations core values are both relied on and sustained. The Team believes these core values will help the Agencys leaders take on the serious challenges ahead, which should yield improved safety, performance excellence, and mission success. The proposed actions in the Diaz Team Report are based on culture-related issues identified by NASA leadership and the work- workforce in the areas of: leadership, learning, communication, processes and rules, technical capabilities, organizational structure, and risk management. The Team believes this systemic approach to cultural change at this critical juncture of the Agencys history will yield a NASA culture that is significantly more responsive and prepared for the promising opportunities of the American space programs future. The seven Diaz Team goals are shown in Table 24. In order to gain a more thorough understanding of the Diaz Teams determiatoons, more detailed examination of the entire Diaz Team Matrix and its 40 actions (Appendix A) and the tables in each of the foregoing chapters is critical. NASA indeed stands at a crossroads. One path is a continuation of the course that allowed the of the course that allowed the Challenger and Columbia accidents to occur. The new path of change may be difficult, particularly at the start, and sometimes the goal is not always in sight. But the rewards for walking this path are far greater than those the old path could ever offer us. For NASA to embark on the new pathway, some fundamental reforms must be instituted. These are encompassed by the 40 reforms Diaz Team actions and seven goals identified in the Report. The essence of these can be captured in three overarching reforms: · NASA must assure that appropriate checks and balances are in place to develop and operate its missions safely, and must undertake the organizational changes necessary to make this happen. The organizationalstructure should help clarify roles and responsibilities of individual employees, work groups and leadership. Every member of the workforce must know his or her. Every member of the workforce must know his or her position in the organization and all must know their position in the organization and all must know their authority, responsibility and accountability for assuring mission success. The entire workforce must also be aware of and understand the rules. · NASA must enhance communications at all levels NASA with a focus on fostering diversity of viewpoints and with a focus on fostering diversity of viewpoints and eliminating fear of retribution. A communications culture must be established with formal communications procedures to ensure effective communications flow up and down the chain of command and across organizational lines. Communications channels should be sufciently flexible to support, encourage, and objectively evaluate all viewpoints, ensuring sound decision-making practices. · NASA must focus on the ways it is managing risk. Safety, mission success and program performance must not be the product of schedule and budget pressures alone. Technological and workforce factors be considered in program planning and decision- making as well. A critical role of leadership is to ensure there is an appropriate balance between requirements, resources and risk. NASA must assure that the workforce has the appropriate processes, tools and technical force has capabilities to accomplish this."

I implore you to read this entire message and ponder upon it before
replying, its quite long and involved. (I think this is the first time I've put my whole argument in one place as a complete unit.) It might be better to reply in manageable chunks. Dave Michelson wrote: Derek Lyons wrote: Except - he didn't actually take any actual action to stop the launch and prevent the tragedy. When push came to shove - he folded. With due respect, I suggest that you're confusing engineering certainty with professional opinion. As a result, you're being a bit harsh. My criticism is not of his behavior at the time, but that the picture he paints of himself today and his behavior at the time do not agree with each other. (I don't think I've been clear, even to myself, that I am not criticizing the Boisjoly of January 1986, but the one who subsequently emerged upon the public stage and asking why the behavior of the latter is not reflected in the behavior of the former.) My seeming harshness springs from the stark contrast between the facts in evidence of the events _then_ and his (and more importantly his supporters) version of them _now_. The problem, as I understand it, is that the cold temperatures on launch day were a new scenario and Boisjoly and co. only suspected that a problem existed. They didn't know for certain. (It was a strong suspicion, but the trends in what data existed weren't fully appreciated until after the fact.) In the absence of detailed calculations or data, others with detailed technical knowledge in the area disagreed. It then became a matter of professional opinion and, yes, engineers often have to agree to disagree. And further study might have shown that Boisjoly and co. had been overcautious. That's precisely my point Dave - the evidence supports the contention that he had an incompletely supported hunch. In that instance it's entirely reasonable for the chain of events to unfold as they actually did. Tragic and regrettable, but reasonable and understandable - everyone makes mistakes from false or incomplete understanding, and in the manned space business mistakes kill. But that does not change reality - everyone in the process bases their understanding on the evidence they have in hand at the time, and their own experience and the surrounding circumstances. They did not enjoy, as we do today, the advantages of 20-20 hindsight and an understanding of the consequences that arose from decisions made nearly inevitably in the circumstances. Now if Boisjoly (and his supporters) stopped there with a mea culpa for their own failings of insight, before calling Dr Guillotine to treat the symptoms exhibited by management, and using today's insight into yesterdays behavior as springboard to seeking ways to improve all links in the chain - I'd have no disagreement. But they go beyond that to the position that "management is evil because they failed to stop the launch and hold up the program based on a few reports and an incompletely supported hunch". There is where we part ways - because that position is to me unsupportable. Management (as you point out) wasn't technically unsophisticated, nor inexperienced (in so much as anyone could be experienced with that few flights under their belt), but they had pressures and priorities of their own. The evidence in their possession at the time indicated that the risk could not be quantified - and thus did not justify canceling the launch and disrupting events downstream. If Boisjoly had been wrong, for him it would have been a tempest in a teapot - one more time when a hunch failed to pan out. If management however had (at the time) believed him to be right (and he subsequently was discovered to be wrong), then they would have been responsible for tens (hundreds?) of millions of dollars in delay, the impacts on Galileo and Hubble, the impacts of public and upper management opinion, etc... etc... To expect them to immune to these pressures is irrational, especially while excusing Boisjoly's bowing to his pressures as being merely human - because the managers too are merely human. Engineers are not universally angels, and equally managers are not universally demons. Each hold attributes of both in equal measures. Boisjoly (I believe) errs in two ways. First in believing the two sets of consequences (his and managements) were equivalent. Secondly in not appreciating the underlying causes of managements decisions. With 20-20 hindsight, we now know that those causes were predicated on the false assumption [belief] that the Shuttle was 'operational' (whatever that means) - a belief that was politically inevitable, with tragic consequences that were equally inevitable. It's ludicrous to hold someone accountable for something that not only did they not appreciate at the time, and which would have required a near superhuman flash of insight to appreciate and to escape the intellectual and emotional fortress in which they had become imprisoned. Even such steely eyed missile men as Gene Krantz and John Aaron, both rightfully lauded for their roles in Apollo, were seduced to the Dark Side - Pre Challenger both supported the Shuttle program and defended its safety. Which is unsurprising, because at the end of the day - they too are merely human. In the days of Apollo they could act in ways they could not in the days of the Shuttle - the times had changed, and they with them. (And as a side note: Why does Apollo era managers and engineers not come under the vitriolic attacks that Shuttle era management does? They too faced their Challenger (Apollo 1) and Columbia (Apollo 13) that arose from their own mistakes and shortsightedness...) Note: I am defending the managers here - I am merely examining the complete picture in its true colors, not the stark black and white, angels and demons terms it is normally cast in. Had Boisjoly and co. deferred to a client or contractor with less technical skill than they had in the interests of expediency, then, once again, your criticism would be justified. Had they not argued loudly and forcefully that the matter required further attention, your criticism would be justified. However, they were overruled by more senior individuals within their own organization and by a client/customer with considerable expertise of their own in the area. That Boisjoly and co. had insufficient time to assemble the detailed calculations or data, convince themselves that their concerns were justified, and present their case, all in the few hours before the launch took place cannot be held against them. My criticism is *not* of his behavior at the time - both Boisjoly's and managements are fairly predictable once you completely understand the situation. (From _both_ sides, Boisjoly's _and managements_, the latter being something few even attempt.) My criticism is of his behavior *now*, where he strongly implies (contends) that he knew that a tragedy was in the offing and that he made every effort to stop it. Neither contention is supported by the historical record. For the first, his own reports fail to clearly quantify the risk. For the second, he did nothing but business as usual - reports, memos, conferences and phone calls. If he did know, or even extremely strongly believed (as he implies today), that a tragedy was in the offing - then that situation calls for those same things, but _not_ worded in the dry and ambiguous phrasing of the work-a-day engineering report - but in strong, clear, and unequivocal wording. That would justify him becoming an arbiter and exemplar of morals and ethics - but that's not what happened. That is the basis of my criticism - ethical and moral behavior demands extraordinary behavior in the face of extraordinary circumstances. I can, and do, excuse him for being merely human and responding to pressures in a way that is predictable and understandable. Equally I can, and do, fault him and his supporters for painting a false picture unsupported by evidence - and then using that picture to support his beatification. In the end it comes down to two simple cases; In the first, Boisjoly is an angel thwarted by dark forces who today testifies to the existence of the demons that defeated him despite his best efforts. In the second, Boisjoly is but one man who played his bit part on the stage, a tragic character but a stock and predictable one. He, and his supporters, wish to paint the first picture. The historical record paints the second. D. -- Touch-twice life. Eat. Drink. Laugh. -Resolved: To be more temperate in my postings. Oct 5th, 2004 JDL |

Derek lyons stated without citations or any support to his statements
in (reference to roger boijolys attempts to convince nasa managers not to launch challenger in the cold weather of jan 28 1986, and the rest of dereks statement is shown below) : "Note: I am defending the managers here - I am merely examining the complete picture in its true colors, not the stark black and white, angels and demons terms it is normally cast in.... That is the basis of my criticism - ethical and moral behavior demands extraordinary behavior in the face of extraordinary circumstances. I can, and do, excuse him for being merely human and responding to pressures in a way that is predictable and understandable. Equally I can, and do, fault him and his supporters for painting a false picture unsupported by evidence - and then using that picture to support his beatification.

The historical record paints the second." Derk please read the information the from the rogers report the caib thought was pertinent enough to include in its final report, along with the diaz report summary, and you will find how your thinking is exactly the type of thinking that must change, (ie nasa managers must operate the shuttle system within it's known safety parameters) for nasa to move forward on the path described by the diaz report. Nasa managers had the authority to did overrule boijsoly, and did in spite of the evidence from the sts-61c srb report listed below, so yes Derek in spite of you're (demons vs. angles) examples and rhetoric, it is the professional responsibility of nasa managers to hold of schedule and monetary pressures for safety, otherwise we are testing Murphy's law. Caib report vol 1 page 100, col2 "SELECTED ROGERS COMMISSION RECOMMENDATIONS · "The faulty Solid Rocket Motor joint and seal must be changed. This could be a new design eliminating the joint or a redesign of the current joint and seal. No design options should be prematurely precluded because of schedule, cost or reliance on existing hardware. All Solid Rocket Motor joints should satisfy the following: · "The joints should be fully understood, tested and verified." · "The certification of the new design should include: · Tests which duplicate the actual launch configu-ration as closely as possible. · Tests over the full range of operating conditions, including temperature." · "Full consideration should be given to conducting static firings of the exact flight configuration in a vertical at-titude." · "The Shuttle Program Structure should be reviewed. The project managers for the various elements of the Shuttle program felt more accountable to their center management than to the Shuttle program organization." · "NASA should encourage the transition of qualified astronauts into agency management positions." · "NASA should establish an Office of Safety, Reliability and Quality Assurance to be headed by an Associate Ad-ministrator, reporting directly to the NASA Administra-tor. It would have direct authority for safety, reliability, and quality assurance throughout the agency. The office should be assigned the work force to ensure adequate oversight of its functions and should be independent of other NASA functional and program responsibilities." · "NASA should establish an STS Safety Advisory Panel reporting to the STS Program Manager. The charter of this panel should include Shuttle operational issues, launch commit criteria, flight rules, flight readiness and risk management." · "The Commission found that Marshall Space Flight Center project managers, because of a tendency at Marshall to management isolation, failed to provide full and timely information bearing on the safety of flight 51-L [the Challenger mission] to other vital elements of Shuttle program management ... NASA should take energetic steps to eliminate this tendency at Marshall Space Flight Center, whether by changes of personnel, organization, indoctrination or all three." · "The nation.s reliance on the Shuttle as its principal space launch capability created a relentless pressure on NASA to increase the flight rate ... NASA must estab-lish a flight rate that is consistent with its resources." http://t2www.nasa.r3h.net/pdf/55691main_Diaz_020204.pdf Diaz report to the caib Page 17 "10.1 SUMMARY In summary, the CAIB Report includes significant technical and non-technical R-O-Fs, which NASA leaders must adhere to in order to help the Agency move forward to meet the challenges of the future.

A postflight evaluation of the SRM structure to determine the extent of damage revealed the following significant items: a. A gas path was noted at the 154-degree position of the aft field joint of the left S_M. Soot was found from the 140-degree to the 178-degree position, and soot was found in the primary groove from the 68-degree to the 183-degree (115 degrees arc) position. C-ring damagewas noted at the 154-degree position with a maximumerosion depth of 0.00_ inch and erosion length of 3.5 inches. The 0-ring was affected by heat over a 14-inch length in this area. b. A gas path was found from the 273.6-degree to the 309.6-degree (36 degrees arc) position of the left S_Mnozzle joint. Soot was found in the primary 0-ring groove over the entire 360-degree circumference. A potential impingement point was located at the 302.4-degree point; however, no 0-ring damage was found. c. A gas path was found at the 162-degree point with soot in the primary 0-ring groove from the lOS-degree to the 220-degree (112 degrees arc) point on the right SRM nozzle joint. 0-ring damage was found at the 162-degree point with the maximum erosion depth being 0.011 inch and the erosion length being 8 inches. The 0-rlng was affected by heat over a 26-1nch length in this area. d. A gas path was found on the outer surface of the igniter at the 130-degree point of the left SRM. Soot was found on the aft side of the outer Gaskoseal, approaching the primary sea! over a 70-degree arc (130 to 200 degrees), and on the outer edge of the inner Gasko seal over a 130-degree arc (ii0 to 240 degrees), however, no seal damage was found. e.

Soot was found on the inside edge of the outer Gasko seal over the entire 360-degree circumference, however, it did not progress beyond the edge of the seal.

Now Derek, for a little more insight into how nasa is attempting to implement the recommendations from the rogers commission, caib report, and diaz report ( and change the thinking you have portrayed in you're posts pertaining to nasa management and culture), you may want to visit the web address below. http://www.onenasa.nasa.gov/NEWS/SMS...mary_Final.pdf "Safety and Mission Success Week Agency-Wide Summary Executive Summary Safety and Mission Success Week was designed to facilitate open communication, and to engage the entire NASA community in addressing the CAIB Report. Each Center Director was asked to champion the week's events and collect feedback from their workforce. After holding the work unit discussions, Center Directors were asked facilitate a data rollup into the main ideas from their Center. Data roll up validated the results of the CAIB and the Diaz Forty Actions. Data from center roll ups were analyzed by a subset of the One NASA Team. The "One NASA Data Team" included members from ARC, GSFC, GRC, and JSC. The team examined the final Center reports and after completing their three-phase analysis arrived at summary descriptions of the themes submitted by the Centers as well as the following 12 cross-cutting themes. Each cross cutting theme was a major idea or theme in at least two Center Reports. 1. NASA should willfully seek out and understand minority opinions. This includes establishing a process to collect anonymous feedback, and holding meetings that encourage open discussion. 2. Resources including time, human capital, and cash flow should be allocated realistically and according to the design standards set forth at project conception. 3. Strategic planning should be relevant for every employee, include human capabilities needed for the future, and be the baseline for on going initiatives. 4. The Agency needs a strategy for leadership development that includes/supports a specific set of skills for all levels of management. These skills should then be used for evaluating performance and making personnel decisions such as promotions and awards. 5. Decisions should be made based on what is best for the Agency, be placed in context using Agency priorities, guide allocation of resources, and be fully rationalized and communicated to the workforce. 6. NASA needs a truly independent safety organization as described in the CAIB report. This organization should serve as a clearinghouse for any safety related concerns from any employee. 7. NASA needs to clarify the organizational structure of the Agency. Current matrix system is too complex and is not perceived as a useful management tool. 8. Safety expertise should exist for every specific discipline within the Agency. 9. NASA needs an increased value on respect for others. All those affected by the decision should be part of the decision making process. Leaders should have the responsibility to provide employees with full information regarding decisions, including options considered, and rationale for making final choice. 10. NASA needs more emphasis on the entire lifespan of projects to avoid being tied up in unnecessary processes, or lengthy approvals that draw resources away from goal achievement. Appropriate procedures should be established, and followed from project conception to completion. 11. NASA should use/design ONE tool to capture expertise and lessons learned in all areas. The tool should be easily accessible, and actively used by the workforce. 12. Contractors should not be used to supply core competency expertise. Building from an inclusive strategic plan the Agency should determine what capabilities should be kept in house, and what capabilities should be provided by contractors. The themes were mapped against the 7 Diaz Team goals outlined in: A Renewed Commitment to Excellence: An Assessment of the NASA Agency-wide Applicability of the Columbia Accident Investigation Board Report. This document is intended to provide a clear picture of the steps taken to analyze the Safety and Mission Success Week.... Page 2 "Introduction As a part of Safety and Mission Success Week, everyone across the Agency was given a copy of the Colombia Accident Investigation Board (CAIB) report and the Diaz Matrix. Management was asked to provide time for employees to read both documents and to hold work unit discussions regarding the applicability of the CAIB findings. At the conclusion of Safety and Mission Success Week, each Center (including JPL and HQ) submitted a brief report that outlined the main ideas or themes from work unit discussions. The One NASA Team was asked to examine each Center Report and develop a set of common themes that would encompass the ideas brought forward by all of the Centers. Note that there was not specific guidelines for reporting data back to Headquarters. Prior to outlining the iterative process used to analyze the Safety and Mission Success Week data, it is important to note that our effort also aligns with recent publication of the Diaz Team's: A Renewed Commitment to Excellence: An Assessment of the NASA Agency-wide Applicability of the Columbia Accident Investigation Board Report. Each Diaz Topic is found in at least two of the cross-cutting themes identified by the One NASA Data Team. In addition, each theme was also identified as a major theme or idea in at least two Center Reports."... page 6 COMMUNICATIONS The comments were grouped into three major sub-topics consisting of 1) disdain for bad news, 2) managers (leaders) not doing what they say, and 3) observations on how we communicate. Based on the data set analyzed, communication is a very important area of concern across the Agency workforce. References to communication were also made in numerous comments in other categories as well. Lack of a process for delivering upward feedback: The predominant theme voiced within the communication topic was that neither NASA nor contractor management wants to deal with bad news or dissenting opinions. The perception is that the all-to-common reaction is to not listen, not understand/believe, not pass it on, and/or penalize the messenger. To follow are a few comments that represent this area of concern. · "Operational and safety information is suppressed at lower levels to the point that most middle managers aren't aware of many concerns that have cropped up. This system results in only good news going uphill, bad news is largely suppressed. This results in a system where risk is accepted by the lowest levels without management having the opportunity to accept risk. This is completely unsafe, and will only stop when upper/middle management actively seeks the dissenting opinions (gets out in the field!)" · "Fear of retribution for speaking against a group decision is clearly an issue at all levels. This includes fear of: Losing contracts, being "frozen" in career path or moved out of position, being passed over for key projects, and experiencing tarnished reputation or professional ridicule." · "It is very intimidating for us or even developer staff to express minority opinions. The thought of going before the [program panel name deleted] to request a change to software is daunting...The program management doesn't encourage minority opinions." Leaders do not follow words with actions: The second most prevalent theme voiced in the comments was that managers (leaders) do not do what they say. This sends a confusing message that undermines trust and respect. Actions must match words. To follow are a few comments that represent this area of concern. · "There is a hesitancy to communicate with someone in authority who has the power to change something or make something happen. We say that people have the right to stop work, but the first time they do and they get jumped on for it, we lose everything that we tried to gain. That's why it is so important for management to support and back the employees." Open sharing of information is crucial to improving everybody's understanding of the universe around us.

That's precisely my point Dave - the evidence supports the contention that he had an incompletely supported hunch. In that instance it's entirely reasonable for the chain of events to unfold as they actually did. Tragic and regrettable, but reasonable and understandable - everyone makes mistakes from false or incomplete understanding, and in the manned space business mistakes kill. But that does not change reality - everyone in the process bases their understanding on the evidence they have in hand at the time, and their own experience and the surrounding circumstances. They did not enjoy, as we do today, the advantages of 20-20 hindsight and an understanding of the consequences that arose from decisions made nearly inevitably in the circumstances. Now if Boisjoly (and his supporters) stopped there with a mea culpa for their own failings of insight, before calling Dr Guillotine to treat the symptoms exhibited by management, and using today's insight into yesterdays behavior as springboard to seeking ways to improve all links in the chain - I'd have no disagreement. But they go beyond that to the position that "management is evil because they failed to stop the launch and hold up the program based on a few reports and an incompletely supported hunch". There is where we part ways - because that position is to me unsupportable. Management (as you point out) wasn't technically unsophisticated, nor inexperienced (in so much as anyone could be experienced with that few flights under their belt), but they had pressures and priorities of their own. The evidence in their possession at the time indicated that the risk could not be quantified - and thus did not justify canceling the launch and disrupting events downstream. If Boisjoly had been wrong, for him it would have been a tempest in a teapot - one more time when a hunch failed to pan out. If management however had (at the time) believed him to be right (and he subsequently was discovered to be wrong), then they would have been responsible for tens (hundreds?) of millions of dollars in delay, the impacts on Galileo and Hubble, the impacts of public and upper management opinion, etc... etc... To expect them to immune to these pressures is irrational, especially while excusing Boisjoly's bowing to his pressures as being merely human - because the managers too are merely human. Engineers are not universally angels, and equally managers are not universally demons. Each hold attributes of both in equal measures. Boisjoly (I believe) errs in two ways. First in believing the two sets of consequences (his and managements) were equivalent. Secondly in not appreciating the underlying causes of managements decisions. With 20-20 hindsight, we now know that those causes were predicated on the false assumption [belief] that the Shuttle was 'operational' (whatever that means) - a belief that was politically inevitable, with tragic consequences that were equally inevitable. It's ludicrous to hold someone accountable for something that not only did they not appreciate at the time, and which would have required a near superhuman flash of insight to appreciate and to escape the intellectual and emotional fortress in which they had become imprisoned. Even such steely eyed missile men as Gene Krantz and John Aaron, both rightfully lauded for their roles in Apollo, were seduced to the Dark Side - Pre Challenger both supported the Shuttle program and defended its safety. Which is unsurprising, because at the end of the day - they too are merely human. In the days of Apollo they could act in ways they could not in the days of the Shuttle - the times had changed, and they with them. (And as a side note: Why does Apollo era managers and engineers not come under the vitriolic attacks that Shuttle era management does? They too faced their Challenger (Apollo 1) and Columbia (Apollo 13) that arose from their own mistakes and shortsightedness...) Note: I am defending the managers here - I am merely examining the complete picture in its true colors, not the stark black and white, angels and demons terms it is normally cast in. Had Boisjoly and co. deferred to a client or contractor with less technical skill than they had in the interests of expediency, then, once again, your criticism would be justified. Had they not argued loudly and forcefully that the matter required further attention, your criticism would be justified. However, they were overruled by more senior individuals within their own organization and by a client/customer with considerable expertise of their own in the area. That Boisjoly and co. had insufficient time to assemble the detailed calculations or data, convince themselves that their concerns were justified, and present their case, all in the few hours before the launch took place cannot be held against them. My criticism is *not* of his behavior at the time - both Boisjoly's and managements are fairly predictable once you completely understand the situation. (From _both_ sides, Boisjoly's _and managements_, the latter being something few even attempt.) My criticism is of his behavior *now*, where he strongly implies (contends) that he knew that a tragedy was in the offing and that he made every effort to stop it. Neither contention is supported by the historical record. For the first, his own reports fail to clearly quantify the risk. For the second, he did nothing but business as usual - reports, memos, conferences and phone calls. If he did know, or even extremely strongly believed (as he implies today), that a tragedy was in the offing - then that situation calls for those same things, but _not_ worded in the dry and ambiguous phrasing of the work-a-day engineering report - but in strong, clear, and unequivocal wording. That would justify him becoming an arbiter and exemplar of morals and ethics - but that's not what happened. That is the basis of my criticism - ethical and moral behavior demands extraordinary behavior in the face of extraordinary circumstances. I can, and do, excuse him for being merely human and responding to pressures in a way that is predictable and understandable. Equally I can, and do, fault him and his supporters for painting a false picture unsupported by evidence - and then using that picture to support his beatification. In the end it comes down to two simple cases; In the first, Boisjoly is an angel thwarted by dark forces who today testifies to the existence of the demons that defeated him despite his best efforts. In the second, Boisjoly is but one man who played his bit part on the stage, a tragic character but a stock and predictable one. He, and his supporters, wish to paint the first picture. The historical record paints the second. D. -- Touch-twice life. Eat. Drink. Laugh. -Resolved: To be more temperate in my postings. Oct 5th, 2004 JDL |

They did not enjoy, as we do today, the advantages of 20-20 hindsight and an understanding of the consequences that arose from decisions made nearly inevitably in the circumstances." Now derek a little historical refresher of the events occuring inside nasa in preparation for the tragic sts-51l mission from the rogers commission, and the documented previous missions (sts-61c) srb o-ring seal failure, might help youre confusion of the historical facts. http://www.gpoaccess.gov/challenger/64_420b.pdf page (26 pdf) or 208 in the report "In the case of STS 51-L, no deviation from normal procedure apparently occurred. This means that the Solid Rocket Motor, containing the seal that apparently failed, proceeded through the usual eight levels of review a t Thiokol's Wasatch Division, Marshall Space Flight Center, the STS Program Office at Johnson Space Flight Center, and the Associate "Administrator's review at NASA Headqarters. The Flight Readiness Review process for STS 51-L began on December l l , 1985, at Thiokol's Utah plant. No information is presented in the briefing charts used that day regarding the continuing failure of the SRM joint seals. The chart entitled "STS-61C (STS-32) (SRM-24) Performance "has only one entry: "TBD [to be determined]." Post-flight disassembly of STS 61-C SRB hardware following its launch on January 12 revealed that erosion of the primary O-ring had occurred in the aft field joint of the left motor. Hot gas had also bypassed the primary seal in the left nozzle joint. Erosion of the primary seal had also occurred in the nozzle joint of the right motor.6 Under the terms of the FRR Policy Directive, such damage would appear to require discussion: "the scope of the review should cover status and issues in areas such as . . . prior flight anomalies. . . ." However, according to Mr. McDonald and Mr. Kennedy, Thiokol normally took about one week to prepare a discussion of problems noted in the initial inspection following SRB hardware disassembly. It would seem logical, when faced with the lack of data from the previous hardware set, to expand the search to other previously-flown hardware. On 61-A, hot gas had bypassed the primary seals in both the center and aft field joints of the left motor. The right motor suffered erosion of the primary O-ring in the nozzle joint. The SRBs from 61-B suffered erosion of the seals in both nozzle joints, with gas bypassing the primary seal of the left nozzle." The Associate Administrator's policy directive is not alone instressing that any available information capable of assisting with an assessment of flight readiness should be presented at a readiness review. Marshall's Shuttle Projects Office policy guidance uses virtually identical language. Under "Shuttle Policy Guidance," it states, "Review Concept: The Shuttle Projects FRR will employ a delta review concept from prior reviews and previous STS missions." In his letter announcing the STS 51-L Marshall Center FRR, Dr. Lucas wrote: Each project manager must certify the flight readiness of his hardware and present supporting rationale and data so the Board can independently assess the flight readiness .. . . Emphasis will be placed on safety of flight and mission success, including potential impact of prior flight anomalies. Apparent in the STS 51-L process, however, is that the continuing SRM seal problem did not receive such treatment. The "delta review concept" referred to above, according to Mr. McDonald, meant that the contractor was obligated to step back only to the previous mission for comparison. For 51-L, there was no previous mission to compare data with, since 61-C had not yet flown. Anomalies on STS 61-A and 61-B were not discussed, Mr. McDonald said, because they had already been dispositioned in the FRR's for 61-B and 61-C. The Marshall Space Flight Center FRR conducted by Dr. Lucas occurred only one day after the 61-C launch. Mulloy's presentation under STS 61-C performance noted that "all SRB systems functioned normally." Under "ascent," the chart shows "no anomalies." There is no indication in the documentation for this FRR that the continuing problem with the SRM seals was raised. The parachute recovery system was discussed at some length. Much of the presentation appears to be drawn from the booster assembly pres entation made at Mulloy's Level I11 FRR on January 3. The onlyrelevant item that mi ht refer to the O-rings appears under "Certification verification status" where no findings from continuing analyses that changes previously established rationale for flight. 'Mr. Mulloy's presentation at the January 15, 1986, Level 1 FRR does not indicate any serious problems with the SRBs. Documentation under "Problems/Anomalies" lists "[IL]~ 61-C flight anomalies." http://ntrs.nasa.gov/archive/nasa/ca...1992075284.pdf NSTS-22301, page 4 "SOLID ROCKET BOOSTER The STS 61-C flight utilized lightweight solid rocket motor (SRM) cases. SRM propulsion performance was normal and within specification limits, with propellant burn rates for both SRM's near predicted values. Solid rocket booster (SRB) thrust differentials were within specification throughout the flight.... A postflight evaluation of the SRM structure to determine the extent of damage revealed the following significant items: a. A gas path was noted at the 154-degree position of the aft field joint of the left S_M. Soot was found from the 140-degree to the 178-degree position, and soot was found in the primary groove from the 68-degree to the 183-degree (115 degrees arc) position. C-ring damagewas noted at the 154-degree position with a maximumerosion depth of 0.00_ inch and erosion length of 3.5 inches. The 0-ring was affected by heat over a 14-inch length in this area. b. A gas path was found from the 273.6-degree to the 309.6-degree (36 degrees arc) position of the left S_Mnozzle joint. Soot was found in the primary 0-ring groove over the entire 360-degree circumference. A potential impingement point was located at the 302.4-degree point; however, no 0-ring damage was found. c. A gas path was found at the 162-degree point with soot in the primary 0-ring groove from the lOS-degree to the 220-degree (112 degrees arc) point on the right SRM nozzle joint. 0-ring damage was found at the 162-degree point with the maximum erosion depth being 0.011 inch and the erosion length being 8 inches. The 0-rlng was affected by heat over a 26-1nch length in this area. d. A gas path was found on the outer surface of the igniter at the 130-degree point of the left SRM. Soot was found on the aft side of the outer Gaskoseal, approaching the primary sea! over a 70-degree arc (130 to 200 degrees), and on the outer edge of the inner Gasko seal over a 130-degree arc (ii0 to 240 degrees), however, no seal damage was found. e. A gas path was found on the outer surface of the igniter at the 250-degree point of the right S_. Soot was found on the inside edge of the outer Gasko seal over the entire 360-degree circumference, however, it did not progress beyond the edge of the seal. There was a slight discoloration of the metal on both sides of the seal over the entire 360-degree circumference."
