Used Ink, you're out of order.
If NASA had known there was a problem, and it was likely to be fatal, then do you honestly think they would have brought the spacecraft back in the full glare of publicity, and all it entails, with the crews relatives waiting at the landing site? Dont you think they might have decided to delay the de-orbit perhaps, and analysie the options?
With regards to Launch / Take Off "debate", stop being a pedantic prick.
You speak as though the crew had the option after take off to just turn around and come back, actually do a full walk-round inspection, or get off at the next stop. Hmmm.
