For Herb's Convenience, a Repost Apollo One, the FBI, and Scott Grissom
As a matter of fact, I'm copy/pasting my answer to Herb's question
from last night because I know how easily messages get lost in lengthy threads where one must weed through all the nonsense concerning various people's sex lives (or lack thereof): Well, now, I guess I'm going to have to repeat what I posted a week ago in order to answer your question (it truly would be helpful if you folks would have read it last Sunday): First, what you choose to believe when I am finished depends on whether you wish to believe Frank Borman or whether you choose to believe the facts. Borman claimed the rocket was safetied. That would have meant that yes, it was actually ready to pull the CM off the stack but no, the pyros had been safetied (by the pulling out of Panel 150; I'm too tired to go into THAT tonight, but if you need those details I'll reiterate THAT part of my earlier post tomorrow.) The evidence, however, indicates the pyros were not safetied until after the fire (note Borman doesn't bother to tell Congress WHEN it was safetied--a cute trick every six-year-old knows.) Here is what happened during the fi 1. Repeated gimbal torque motor signals. 2. SCS oscillating in roll, pitch, and yaw. 3. LEV accelerometers oscillating in pitch and yaw. 4. RCS jet driver activation commands in all 16 flight directions. 5. 12.4 and 13.6 seconds: Roger switches the entry batteries over to the main batteries, which not only ensures the suit compressor will continue functioning but also completes the Emergency Detection System circuit. 6. 17 seconds: They receive a Program Check Fail and an Error Detect Fail. These are abort failures. They generate a guidance and navigation warning, two Master Caution and Warning, and two DSKY lights. 7. 18.5 seconds: Gus rotates the T-handle to the translation controller 360 degrees clockwise and switches thrust vector control on. THIS SWITCHES FROM THE APOLLO GUIDANCE COMPUTER TO MANUAL ATTITUDE CONTROL. So the question is: Why is he worried about that in the middle of a cockpit fire on the ground UNLESS he is afraid the LEV is about to light? And, as I mentioned before (and this was so interesting to Stu Roosa that he ordered close-ups of this switch) the BMAG switch had ALSO been turned off. The BMAGS do not have to be turned off in order to engage manual attitude control; however, in the event of a guidance and navigation failure, the BMAGS serve as a back-up so they will CONTINUE TO SEND ERROR MESSAGES TO THE AGC. Again, another indication Gus was worried the auto abort was either about to be or already had been engaged. Finally, for those who are about to argue THIS point: Once an abort has been triggered, it cannot be stopped simply by switching off the EDS. There is a failsafe built in so that in the event of an electrical failure an auto abort will continue. The only way to stop it is by switching to manual control. |
