They have a large surface area combined with a cup shape. This would in the least create a large pitch variation and adverse yaw if not opened on both sides. The forces exerted against the frame and hinge would be large given the long length. If the hinge did not give out, then at least a large stress will be placed on the subframe there. If the door did come off then the risk to catastrophic damage to the tail seems great. Wasn't there an indicdent mentioned on the list where the door popped open in flight causing it to tear off and hit the tail?

This time the door didn't rip off, but got badly mangled. An open door like that can ride nice and stable until the 80kt airflow catches it wrong, and then all hell breaks loose! Take care.....
