1979, Sunflower Gliderport, Standard Class Nationals. Flapped gliders were permitted to race in Standard Class, but they must either have their flaps locked in position, or have a timer installed to indicate if the flaps were not at zero. They were permitted to use the flaps up to three minutes per flight. This was to permit use during the critical takeoff and landing phase, and kind of important to those flying PIK-20Bs. Charlie was assigned to be "The Flap Fuzz". His job was to check the seals and timers on all flapped sailplanes when they landed. Since people were landing all around the airport, Charlie needed a way to get around. He was given a small, 100 CC dirt bike. That would only drive in first gear. So, there was Charlie the Circus Bear on this tiny little motorcycle, screaming like mad, doing 10 MPH across the ramp, scurrying from glider to glider when the gaggles came home. And he did it all with a big smile.

"...have their flaps locked in position, or have a timer installed ..."

Sounds strange. I can imagine ways that the flap handle could be locked in position or sealed (maybe "warranty void if seal broken" labels). But how does a flap "timer" work?
