It is amazing to see a large jet performing moves like that, but every time I watch the videos I expect it to end with a large smoking hole in the ground. He got lucky.
I once saw a boy racer speed his Corsa the wrong way down a one-way street late at night. He got lucky too and there was no traffic coming the other way. If someone had been though (and he could have been Michael Schumacher for the difference it would make) then the result would have been a smoking hole.
You can't control everything and I'm surprised that the Chief Pilot would put himself, his plane and his crew in such a tight spot. Would there be such support if this was a pilot who was fresh out of school?
