Shock! Horror! Door pops open!

I modified a 182 and 206 for jumping some years ago. After removing
the hinges I cut off a triangle at the bottom forward corner and
riveted it to the frame. That was so I could hinge it at the top and
the door would clear the strut. Fabricated a new latch that went fore
and aft and a new door handle in the middle that you could twist.

To work it, the pilot unlatches it and pushes out hard. The
slipstream makes it climb until it contacts a rubber bumper under the
wing. Dif pressure keeps it firmly there while the crazies leave.
The pilot pushes left rudder and the door slams shut. He reaches over
and twists the handle then heads back for another load of crazies.

My point is, Im sure with the Piper-style door, you can close the
vents, slip the aircraft and latch the door a bunch faster than
heading back. Am I wrong?
