Sure, but that's not the part I had a problem with. Korean Air, after all, had an incident in the 90s where the captain overruled the strenuous objections of his copilot, resulting in a fatal crash.

The main issue I had with the post was that he's claiming this to be the case purely on the notion that the copilot did not speak during the crash. That's severely reaching, and smells a lot like fitting facts to a predetermined conclusion rather than the other way around.
