Another amazing part of the whole WOD thing, is their extremely popular WW1 Gaggle Flight where as many WW1 airplanes takeoff in mass to get as many vintage warbirds into the air at the same time. Today in the Friday Gaggle, the number of dogfighting aviators was 33. An impressive number that would have been impossible in the days of 72mHz radio systems. The new frequency hopping spread spectrum 2.4GHz radio systems make these mass flights possible. No mid-air mishaps this time and you could not throw a stick without hitting a plane during the Gaggle. Oh yea, and the sound–amazing!
