9 - I do not know of/about "Richard Feynman" or his theories, but I do know about the o-rings. I know that the o-rings had been leaking for years, since they changed the putty, and just about every launch had 'near burn throughs' on the o-rings. I know because I and my brother personally talked to those servicing the shuttle SRB's, and saw photo's of many of the near-burn-throughs. And these were the guys who actually worked on the SRB segments.

I also know that the o-ring problem was so serious, they completed a design fix 17 months before the Challenger murders. 17 MONTHS. And yet NASA management wouldn't/couldn't get the gumption to fix the problem, even after it was designed.

So, I will defer on his theory that anti-gravity is impossible, particularly, since, even today, WE DON'T EVEN KNOW WHAT GRAVITY IS !!!!

Same failure mode recently -- many foam strike damages noted on recent shuttle flights, yet the level of concern didn't correlate with the level of foreseeable loss.
