[quote="APG85"]Pretty neat picture of Space Shuttle Columbia taken by a USAF ground based camera a few days before she was lost on re-entry. Unfortunately the payload bay doors masked the damage to the wing leading edge...
If they had only seen the damage, it would have validated the concerns of the mid-level engineers, who only days before viewed the launch video and made eerie predictions.

It still bothers me to this day how NASA and Boeing were able to come to the conclusion that the damage posed no problems, without so much as a "let's make sure and get some ground based photos!" You can't tell me they didn't come to the same conclusions as the lower level engineers? Was the crew on board even aware?
The truth is, if the damage was found there would not be much that could be done. They could not reach the ISS. They could not ready another orbiter in the time frame required before the Columbia ran out of fuel and supplies. Even if they could, how would you make a transfer of the crew? Bring 7 EVA suits with the rescue shuttle? I don't think Columbia even had an airlock as it was never intended for ISS construction missions.
The only difference would be to reenter and hope for the best. Plan for Edwards to avoid debris over populated areas. Plan for a bailout if the wing was compromised.
