Yes, according to: http://history.nasa.gov/skylabrep/SRch9.htm and the second craft (Skylab B) mothballed. Was that a "management failure"? If you spend many millions of dollars building a spacecraft and make plans to launch it, if you already have a launcher for it too, and if management then calls it off in favor of something "better" (the space shuttle), that DOES look a management failure. -- /\ Greg Kuperberg (UC Davis) / \ \ / Visit the Math ArXiv Front at http://front.math.ucdavis.edu/ \/ * All the math that's fit to e-print * |

It seems far more dangerous to me. If you are going to physically wack the wing, you can do that then get away from the thing fast, since you're in control and planning ahead. But doing it indirectly would require pretty fast reaction time, I'd think. Or maybe I'm not visualizing this well and there's little chance of an unintended collision from the destabilized V1?

It wasn't intended. ;-) I'm not sure but that what they did was more dangerous, when you consider how little we knew about spanwise flow and wingtip vortices (vide the XB-70 and the F-104 collision). Now that's interesting. Are you saying that wasn't a result of a physical collision (I'd always assumed that it was)? That it occured because of aerodymamics alone? Or that the instability of the proximity caused the actual collision? -- simberg.interglobal.org * 310 372-7963 (CA) 307 739-1296 (Jackson Hole) interglobal space lines * 307 733-1715 (Fax) http://www.interglobal.org "Extraordinary launch vehicles require extraordinary markets..."

For obvious reasons... but lets not forget that as more second and third world countries become developed, then that demand on oil will grow. The Green study took that into account. They measured rising efficiency against growing demand to arrive at the mid 2030s. Done correctly then. Other studies attribute more to conservation and improved efficiency Improved efficiency? Good luck to them, when car manufacturers like to make lots of fuel hungry cars as well. and use of alternative energy to come up with much later dates. Many of them busy on fuel cells these days, where they are also trying to get the fuel into a different form. Iraq is a huge country to search, Ever thought about using technology? As it is not like they have to personally turn over every rock. Unfortunately, real life is not "Star Trek". I never said it was, but there is a lot of technology that you can use. As lets not forget how this same technology found the likes of those mass graves in former Yugoslavia. You can't set scanners to maximum and find Saddam's stash of Smallpox warheads. They actually do have to turn over every rock, more or less. In this case "turn over rocks" equals "search every building, warehouse, garbage dump, etc." Try deep underground in his chemical and biological weapons facility. And you can't tell me that you don't have the technology to find holes in the ground, where even the Mars Express is carrying technology not unlike that to search deep into the Martian crust. More US propaganda I see. Try you average Iraqi civilian who are simply very annoyed at the US occupation of their country. Only in certain areas, it seems. Not much around Baghdad, for example, That would be odd given that this should be more of a problem around population centers. where support for the US is still quite high. One thing I found interesting when I was watching feeds from Baghdad was how a lot of people were wearing the green of Saddam's loyal troops, and where these very people mixed in between the civilians as if they were one in the same. I just see it a little hard to see how a population who was pro-Saddam could change so quickly. And even on the news they said how his most loyal troops was in this area. Anyone with some intelligence would avoid direct conflict with their advancing troops (and B52s) and pick them off one by one later on. Considering the lack of information coming out of Baghdad these days I can only feel that it is not good. Once Saddam is confirmed dead Dead? Reports are around that he has been captured, which makes it a little unjust to now execute him. I've seen no such reports, There was a report that he had been captured in his home town, which is news that spread like wildfire. The US reports no news on this matter, which is also something they would do while they await DNA tests to confirm his identity. I doubt it myself though, when with all that money he took he is most likely living in a different country by now. but will welcome a War Crimes Tribunal for that monster. Yes, but the trial of a certain Serb was not going too well the last I heard. However, I think Saddam will prefer to die fighting, like his sons, rather than be taken alive. Perhaps, but he is bound to have a cushy life if he lived on trial or no trial. Saddam could be even harder to nail down. and the Iraqis believe it, The Iraqi people already know that he is gone for good. No, they don't. So what would you give the odds of him returning to power? Somewhere around zero would you not say. See, they know... Al Jazeera, among others only two days ago broadcast what was purported to be a speech of Saddam encouraging "his" people to rise up against the Americans. Yes, quite interesting, when one day it is that he is captured and the next he is like walking through the streets. Now, the Iraqis know that is laughable, Certainly. but it also reminds them that the man is still on the loose. And can do nothing, when his call for other arab nations to join him went unheard. They will remain largely uncooperative with the US until they know he's arrested or dead. He is nothing more than a figurehead these days, when he simply lacks the ground support since the US has been knocking off his most loyal followers. I do not see things changing much from what they already are. Just offer them lots of money, a new identity, then a place for them and their family to live in the U.S or elsewhere. That has been done. No reward-seekers have been forthcoming, because in Iraq the penalty for ****ing off Saddam was often death. And yet someone has already collected the reward for the death of his two sons. Now I am thinking that this whole story got warped to using a different name... If you were lucky, it was a long prison sentence. And the Iraqis are not yet convinced Saddam is gone for good. Time will tell all, but as I said I don't believe that you will be finding people wanting to talk about his WMD. Or at least Saddam's personal emergency stocks would have been destroyed long before this War came about. Or immediately before the war, which is a possibility I freely admit. In any case Saddam was not the type of person to launch a WMD attack on the West, when he has never done so to date. The western leaders like to bring out such fear in their public. But there is no question that Saddam had it even in the mid-90s. Even the UN and Bush's critics admit that. Perhaps, but you have no WMD now. And since your President went to War based on that very reason, then not yet finding any is at best embarrassing. Saddam failed repeatedly to offer evidence it had been destroyed. He turned over about 40,000 pages I recall all about his weapons programs and how about he did not have any. I watched the US talks at the UN and their evidence was at best laughable. The UN took the position "prove it's there and we'll approve the war". Yet the UN never did approve this War... Bush took the position "prove its gone and we won't go to war." Not really. The UN was pressing weapons inspectors, which Saddam agreed to near the end. And of course the report then said that he did not have any, where more than a few weapons inspectors are happy to say they do not believe that he has any. It is quite clear that the US wanted War all along, where all they wanted were things that would not happen, like with Saddam and all his followers leaving the country. And Saddam almost certainly did still have it. Prove it. :-] He may have panicked and destroyed it in the final weeks before the war when it became clear that the US was going in with or without UN approval. Or possibly long before. In any case the key factor here is that all the time they do not find Saddam's secret WMD stocks, then their whole reason for going to War has not been validated. Also it is really pointless looking in places like warehouses, when Saddam has known about people looking for his WMD for years. And so if he had any, then they would be the best hidden items in Iraq. Very deep underground and no doubt wired with explosives to insure that no one ever does see them. Funny how the U.S has crap loads of WMDs. And they have even used them on civilians once before. We used them on the Japanese, by the way. Yes I know. And Saddam used his own weapons in the Iran/Iraq War, where he was also kind enough to not drop them on US troops the first time around. Not unexpectedly, the Japanese supported the war to remove Saddam. Then the US supported and even armed Saddam in the Iran/Iraq War. Then lets not forget how many people the trade embargo killed, when the UN oil for food program only came about after it became a problem. The embargo could have been ended at any time by Saddam and his sons surrendering power. Come off it. That is the one thing that everyone knows is not going to happen, where anyone who demands it already knows the answer. The US made no secret of the fact that it wanted Saddam gone. But Saddam and his sons wouldn't leave. And as Saddam once pointed out that it was a silly idea and that President Bush should leave his country. They wanted to remain in power at any cost, even if that cost was thousands of civilians deaths. You cannot blame someone for "being", when the US and UN imposed a trade embargo off their own backs. Not that this was very effective mind you, when companies looking to make profit are always interested in trade. Anyway I am only happy to tell you the truth, I've heard very little truth from you. Outright falsehoods is closer to an accurate description. Then go and prove it, when all you have are different if not odd ideas. Ideas that I would not expect a US citizen to have, when the politicians like to use western media to air their biased views. that this is all about is that Iraq does not like the US, That remains to be seen. Well I was talking more in a country sense, but you can also read it in the growing number of dead US soldiers each day. your president is on his 9/11 crusade against his enemies, where he also hopes that doing this will solve all those Middle East problems. It's a good start. Perhaps, but a lot of people will still consider it wrong, when they do not believe that the state of Israel should have been imposed on the region. So all the time that people see that their former land is being occupied by others, then peace is unlikely. They want them gone and they are prepared to blow themselves up to see it happen. Yes Iraq is now better off, but the dead and the families of those dead won't be thanking you. Fortunately, we are not asking for or expecting their gratitude. And I doubt you would get anyway. Saddam good or bad was an Iraqi citizen, where US and UK troops are not Iraqi citizens. More likely you will pee them off and they will bring you another 9/11. We got 9/11 even without doing anything to the Iraqis, Al Qaeda, or the Taliban. US Forces in Egypt set one Osama Bin Laden off on his road to making a smudge in the US history books. Combine that with the US imbalanced handling of Israel problem, then that made for one extreme guy looking to get the US involvement removed from the Middle East. He did hate you with due reason. And the Taliban were just some extreme religious guys who were prepared to put up with him. Even Iran has an extreme religious leadership, which is another country on the US War list. It was our mere existence that they hated. Not quite, when it is more a question of what you do than who you are. Some people would say that 9/11 was just the US receiving back what it has been dealing out for years. As like it or not the US has been strongly on the side of Israel in the region, where we all know what Israel has been up to. So your assertion that we should instead do nothing now does not make any sense. I never said that nothing should be done, but a question is if the US once again proving its might on the Middle East going to help here? Hell they may even force the Palestinians to accept their own country, but this won't end the problem. What you should understand is that there is no right and wrong, when it is only degrees of helping some and harming others. If you will get another 9/11 I don't know, but this seems to me dependant on not annoying those in the Middle East and elsewhere. Cardman. |

If it made sense to mothball Skylab B, then Skylab A just wasn't very important, which implies an even bigger management error. You have to understand that NASA doesn't control its own funding. They were able to get Congress to approve funding for a backup Skylab, in case the original one didn't make it into orbit, but when it came to flying it, they were faced with having to shift funding from Shuttle development (putting the Shuttle behind time from the starting line, as it were). Congress was unwilling to fund both Shuttle development *and* flying a second Skylab. And at that point, the Shuttle represented the future of American manned space flight, while Skylab was what it always was -- a way to use up leftover Apollo hardware. With the mindset of the time, it's easy to see how they came up with the decision they did. It wasn't "bad management," it was simply a choice between a limited number of additional missions with what seemed at the time as dead-end technology vs. development of a tool that promised to open up access to space for much less money. (So, that was a pipe dream, but not a pipe dream generated from bad management, just a pipe dream that happens when you let the salesmen control your planning, LOL.) But back to the main reason why Skylab B wasn't flown -- no one ever said Congress was intelligent in how it allocates resources. But NASA is somewhat over Congress' barrel when it comes to those things on which it can spend money. -- Do not meddle in the affairs of dragons, for | Doug Van Dorn thou art crunchy and taste good with ketchup | |
