One Thiokol engineer objected and his boss overrid his objection. The engineer was right and I have a lot of respect for him, but the temperature was probably not the issue, just the o rings. He was actual right for the wrong reason. People do the best they can. Perfection should not be expected when pushing the envelop. Atleast one person objects about every launch. The problem list that managers work is 100's long.

Couldn't they have sent up Bruce Willis or something?

are you conceding that potentially valid objections are overruled then, because of schedules or costs? ... that was my point ... there was some reason his manager overruled him ... and if I understand correctly, those barriers were ostensibly removed after the 1986 incident ...
