This is an experimental version of a flying boost/glider model built by Estes Industries in 1957. The model is made mostly of balsa and has a plastic parachute. 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 is launched from a launch pad, with a hand-held launch controller being used to ignite the motor.
The model was donated in 1973 by G. Harry Stine, one of the American pioneers in the field of flying rocket and missile models.
