Sorta true, but maybe sorta misses the point. Several minutes before its complete destruction, there were plenty of signs, for instance, that the space shuttle Columbia was doomed. At seven minutes before destruction, several people (including Freepers) reported bright flashes taken for serious problems. At five minutes before destructions, numerous sensors quit signalling. At four minutes, Columbia started rolling. At one minute, ground control recognized loss of signal which likely meant loss of landing gear. At 30 seconds, radio communication was lost.
Columbia wasn’t lost during launch. This escape system would only help during launch. Challenger’s onboard computers only detected anomalies a few hundred msec before the vehicle came apart.
