With ref to the large 'pull' that P1 surprisingly used.
He was plainly trying to go around.
OK, that sounds daft but nowadays pilots are taught to GA at every eventuality.
They teach that pretty much every problem will be solved if you only, perleeeease, will just take it around again!
So when it turned nasty, I bet this guy thought 'I know! Go around!...........Heave!'
Does anybody think that this was his version of a stall recovery? Nope.
This ever increasing reliance on the go around to solve all our problems is pernicious, misleading and flies in the face of proper airmanship.
