Did you miss the "gear up" part of my comment?
see quote below, I know I couldn't find 'gear up'.
I think you should blow up if you land gear down over 150mph 50% of the time with the percentage being lowered as your touch down speed decreases to where you would die only 10% of the time for a full stall landing.
In AcesHigh if you attempt to belly land with the Gear Up at over 150mph, 100% of the time you'll explode.
I was actually at an interview for an apprenticeship at McDonnel Douglas when this occurred and privy to the information.
As for privy to MD info etc as an interviewee apprentice icepac, that holds absolutley no credibilty at all.
