No, he means launches. Columbia was mortally damaged by the debris coming off of the external tank during launch. It was a problem that occurred since the beginning of the program that was never resolved. It's a problem specific to a sidemounted vehicle. Columbia would have reentered just fine had it not occurred exactly when it did.

Which shuttle program was this? Can't find any history or data on 2 shuttles disintegrating during launch. Found information on 1 NASA shuttle breaking apart during launch in 1986 and 1 breaking up during re-entry in 2003.
