My guess is that b****y great propeller in front; very close to the ground in a wheelie. You would want to slow down very, very gently. Or maybe you would have to keep up an airspeed for a wheelie that takes you into the far hedge, what with slowing down carefully as well. Or maybe Spitfire pilots are/were just so good at it they do 3-pointers out of pride in doing something properly.
I dunno, is what it boils down to.
