Re aztec doors,
yes the storm window helps but doesnt cure the problem.
When the door pops the aircraft yaws and one puts on rudder. The problem for most normally designed pilots you can't reach the door and keep the rudder pressure.
The sideslip, yaw, rudder pressure and reaching the door which is at least a foot open is a challenge !
Of course having a passenger would help !!
It also happens after takeoff so you have to climb if you want to mess around !
