Indoor OT flying in Oklahoma City
There is an active indoor flying club in Oklahoma City. The following were taken at their event in April of ’07. The Gotha and little Nieuport are walk behind gliders. (note the size of the US dime in front of the Gotha) It is sort of man made slope soaring. See here for how it’s done http://www.geocities.com/x_surfer2004/ . The Fokker V23 is a classic rubber powered free flight.
