In the 60's, there was a 707 that suffered a bomb explosion, damage was significant and the crew did the "high dive" emergency descent, as practiced in training. The plane broke up in the upper teens, IIRC. OTOH, a AF C-141 had aft door failure, most of the crew were rendered semi-conscious from the rapidity of the decompression at FL 410, I believe. The co-pilot wasn't sure what tp do but by then training mentioned structural failure and he did a gradual descent and saved the plane and crew. Lockheed, who rebuilt it, was positive that the plane would not have survived a high speed descent.
