>why did the plane tip over? were they trying to turn it around?
Asymmetric thrust caused by right engine failure/fire.
This would cause the plane to yaw to the right causing loss of lift on the right wing resulting in the plane rolling to the right.
As a transport plane the three crew members would not necessarily have had parachutes.
To bailout they would have to get out of the cockpit and back to a side door in the main cabin area.
As a prototype plane their main instinct may well have been to try and save the plane rather than themselves.>14376188
