Left wing stall due to the bank angle limits being breached for that aircraft with no available remaining altitude at which to recover the stall.
The crew are all dead because the reckless pilot (who had a lengthy history of hotdogging show off moves) input too much bank angle at too low of an altitude at too slow of a speed.
I’m sure the “bank angle” and “minimums” alarms were blaring in their headsets before the stall. Even the poor enlisted crew on board who had no window could feel and hear their impending deaths in their ears.
That must feel so helpless, watching the ground come up into you, strapped into a jump seat while an arrogant flyboy seals your fate.
