This is a flying space plane model built by Estes Industries in the 1960s. It is not known whether it was flown. The model is made entirely of balsa. A solid propellant rocket motor propels the model, and then at the end of the vertical flight it forces the release of a parachute. The model is then retrieved and can be used again. The model was donated by G. Harry Stine, one of the American pioneers in the field of flying rocket and missile models, in 1973.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
