One obvious constraint as to possible causes of failure is noticing the trajectory of the shuttle remained fine through the turns preceding the descent over Texas.

If the cause was a random insulating tile failure or control surface defect, such a defect coud easily alter the trajectory considerably.

Does anybody have a link to the shuttle's programmed trajectory pattern or decision points at which new optimization paths were calculated?
