I did mention he was my new hero. I also agree he's barking and a genius took, with a little idiot thrown in for good measure.
But, is it really as dangerous as it might seem, though it may be a little sporty for some (like my own) tastes? No plan B? What about an engine start?
If I was him, I would not have done a deadstick take off right away. Would have been a careful build up, taking off with partial power, taking off at idle, and seeing how much margin you have. This is if you can get over the fact that just landing on top of a mountain like that is nuts period. I'd never do it. I'm afraid of heights.
