How much time do these guys have?
What is the typical total time for the crews involved in these incidents? I am a corporate pilot, and all of these mishaps occured back in the 60's with Lear-jets in our end of the business.
Do the airlines teach high altitude aerodynamics at all, or do you put a turboprop guy in as PIC without much training? All of these things have happened before, history is being repeated. It is not magic up there. Keep your speed up, and you will be fine. I would soil my shorts if I was doing .70 at 410.
