However many thousands of hours they might have, some are obviously not aware of the fact that IF YOU ATTEMPT A STEEP TURN WHEN FLYING LOW AND SLOW YOU ARE DEAD MEAT!
They assume (presumably due to lack of training) that they only need to apply opposite aileron to level the wings! This is intuitive but fatal. They do not realise that in this situation the drag caused by opposite aileron merely stalls the inside wing promoting a spin.
Google Fairchild B52 crash for a perfect example. You can see the pilot applying opposite aileron (spoilers) as the plane, at 90deg bank spins into the ground.
The key question with regard to the Yeti disaster is, did either the PF or the captain have recent training on incipient spins? Either on a simulator or an aircraft?
All of this assuming of course that there was no defect on the aircraft.
There are lots of references to what you describe but it is doubtful the crew would be attempting to go much beyond 30 degs of bank. More likely, the steep bank is caused by the stall, both engines are turning, it has hi-AoA, looks a clean wing and if they then used rudder to align and aileron to control bank it would have been a classic skid stall.
Unloading immediately at that altitude is unlikely to have saved them and it is unlikely they will have gone beyond the approach to the stall in training. Paul Ransbury from APS has a bunch of presentations about it from their UPRT sessions on traffic pattern stalls.
