They had a plain, old round magnetic compass and a watch and they used landmarks on the ground. They did it with skill and familiarity with basic flight instruments. They were really some amazing pilots.

But that's not what qualified me for membership. It was the (1963 documentary) film I made, 'The Seat of Your Pants,' which featured a bunch of OX5 pilots -- old-timers flying antique airplanes.

According to the club rules, you had to have flown an OX5 or have been a mechanic who had worked on the engine.
