The only common factor appears to be poor command by the Captains concerned.
Sounds like you used to fly single piloted.
Today we tend to fly as crews. There was a discussion here of PF and PNF botched coordination and disagreement on a go around decision and Flyingphil cited the CI TPE crash as an example of how not to do it. I replied with a mention of the eerily similar CI NGO crash. My apologies if we were out of line.
Caveats, Flyingphil is not a pilot and I drive the lav truck so we always appreciate your superior views here.
