Above is an article in the Wash. Times. "Just before it disintegrated, space shuttle Columbia experienced an abnormal rise in temperature and wind resistance that forced the craft's automatic pilot to make rapid changes to its flight path - possible evidence that some heat-protection tiles were missing or damaged, NASA said Sunday."
I had read very early on that the shuttle had been jinking, and the person who mentioned it surmised that the pilot may have been trying to slow the craft for the landing. According to the above article, it was the automatic pilot that was doing that. Could be that the torque involved in those manuevers in addition to whatever was causing the sudden rise in temperature contributed to the break-up.
Very missleading article. The computer corrections were small, but larger than seen before, indicating a drag problem on the left side.
The orbiter also was undergoing a normal side to side motion to scrub off speed. This guy has the two confused.
