Letov LF 107 Lunak
Perhaps one of the most exciting sailplanes ever produced. Capable of flying at 250mph, or with flaps deployed at less than 45mph for climbing in thermals. Originally it was used to train MiG pilots. Sadly very few survive today due to an order from the Czechoslovakian airworthiness authority ordering all 200 Lunaks to be destroyed in 1952 after one broke up doing aerobatics.
