Columbia was not lost because NASA lacked warning signals. Foam had escaped from external tanks before, a large bipod-ramp loss had occurred on the flight immediately preceding STS-107, launch imagery showed the new strike, engineers sought better images, and the in-flight analysis carried major uncertainties. The accountability failure was that these facts did not acquire enough authority to stop routine reasoning. A breach in the left wing destroyed the vehicle during re-entry; a system for classifying, escalating and disproving hazards had already converted repeated noncompliance into accepted experience.
