When a bubble door pops open next to you it will make you sit upright!
With a bit of pedal you can get the door into a position to latch it properly....without much difficulty. Reducing airspeed and yawing the aircraft is enough to work the problem out.
I had a door do that three times in one short flight....it was warped all out of shape as was the helicopter from way too many thousand hours of Logging.
This should not have been a fatal accident.
