This is a Mark I Rock-A-Chute flying rocket model, one of the first ones built by the flying model pioneer Orville Carlisle. The model has a balsa body, cardboard fins, and a paper parachute. A solid propellant rocket motor propels the model, and then at the end of the vertical flight it forces the release of the parachute. The model is then retrieved and can be used again. G. Harry Stine, another of the American pioneers in the field of flying rocket and missile models, donated it to the museum.
