With wings over the fuselage and fixed landing gear with a small step like a ladder tread on the it. There were 3 jumpers and the jump master. He gave us three instructions as part of the jump...
Sit in the door, which meant put your feet out the door on the tread.
Get out, which meant stand outside of the airplane on the little tread. You were bent over because the wing was over your back and you had two hands on the wing strut. You could look at your feet and see straight down 3000 feet. That was actually easy to do.
The third command was let go.....
