My mental model is that the biggest risk is the turning turboprop. The rest of the dynamics fall out from that: during the dive, the engine on the divers' side is already off, and once the stall happens, the pilot cuts off both engines (to avoid a spinning engine hitting anyone), dives to gain speed. Being inside the plane as a jumper during the recovery was probably the least pleasant -- normally one doesn't have a seatbelt in that scenario. I think at 0:54 one more person falls out the open jump door?
