Didn't we have a pic floating around the forum of a guy hand-propping his aircraft in midair?
Don't know about that, but I don't remember now if it was Bob Hover, or Bob Reeve that he and his partner used to do mid air refueling in their Aeronca, A C-3 if memory still functions this late at night. One would fly and the other would step out on the strut to pore fuel from a can into the header tank.
I also got to ride with a 7AC pilot on his way to OSH one year who showed me how he transfered fuel. Apparently the J-3's he was traveling with had just a bit more range. so he had a can in the back seat and hand pump strapped to the side of the cockpit. He'd reach through the side window, stick the hose in the header tank, then pump the fuel in. gotta love those old planes.
