NOW maybe they'll look at their antiquated launch systems with a more pragmatic eye.
But it's a desperately sad day for all concerned. Of course I feel for the astronauts' families, but I also feel very sad for the ground crews and mission control people. Losing a spacecraft on your watch must be as bad as losing a family member.
It's perhaps even more ironic that it happened on ST-107, because it was a pure science mission - no spacewalks, no satellite launches, no hush-hush aspects. Just plain science, trying to expand the boundaries of human knowledge.
It makes me WILD that NASA felt that they had to state that there was no reason to suspect terrorism as almost their first announcement. There are enough things that can go wrong with one of those babies without any outside help, that's for real, and using a 22-year-old prototype is hardly a safe proposition, is it? Having said that if I was offered the chance to go up in a shuttle, I'd be camped at 39B within a day to ensure that I made the flight.
From the news reports, my guess is that the shuttle lost attitude during the reentry phase, because it was far too low when it flew over Dallas and Plano, creating sonic booms along its path. They have an attitude leeway of less than 5deg, and no realistic way of recovering if they get out of shape. I don't have any idea of why it might have lost attitude, though. I hope they can find out.
Damn!

Here's a link to the MSN reports: http://msnbc.com/news/857733.asp?0cv=CA00Beef-up security, Israeli aboard...that's why NASA had to come out immediately and state whatever it stated about no terrorism [and I, too, shuddered when I read the word]. I haven't seen NASA's statements on the matter, but it makes sense something would have been stated under the circumstances. Sharon hasn't said anything public yet. It's all too terrible--hard to think of anything to say at all. Just want to know more about what went wrong. Thanks, D., for your input here. T.

The Crew of the Columbia: In Memoriam Richard P. Feynman's Minority Report to the
Space Shuttle Challenger Inquiry
Conclusions: (abridged)
If a reasonable launch schedule is to be maintained, engineering often cannot be done fast enough to keep up with the expectations of originally conservative certification criteria designed to guarantee a very safe vehicle. In these situations, often with apparently logical arguments, the criteria are altered so that flights may still be certified in time. They therefore fly in a relatively unsafe condition, with a chance of failure of the order of a percent.
Official management, on the other hand, claims to believe the probability of a failure is a thousand times less.
This difference has unfortunate consequences, the most serious of which is to encourage ordinary citizens to fly in such a dangerous machine, as if it had attained the the safety of an ordinary airliner.
For a successful technology, reality must take precedence over public relations, for nature cannot be fooled.
~ Richard P. Feynman 1986

Re: Space Shuttle Explodes
I hope the Feds nabbed him. (eBay ivalidated the auction and took all the info down, except for the main menu).
