BOAC
As I have said before, once the crew found themselves with an 'unknown' ?60? degrees AOA at the top of the 'zoom', they were well outside any training environment we could contemplate.
The AOA wouldn't have been high at the top of the zoom. It would have increased to its terminal, large value as the plane gained downward velocity, creating an upward component for the wind, so to speak.
I'm thinking they had a chance if they'd been able to act quickly, but once they were falling fast the dip needed for the nose might have been more than they were prepared to contemplate - or would have resulted in greater forces than the airframe could withstand.
