Airplanes and Rockets website visitor Steve O. wrote asking if I had any information on the Skystreak model made for the Jetex engine. It had a lightweight molded plastic airframe modeled after the Douglas D558-1 Skystreak with a motor clip on the bottom. Rather than being designed to actually fly, it was intended to "fly" along a string stretched taut between two supports. Those aluminum bushings in the nose and tail accommodate the line. Evidently these things are very difficult to obtain, but Steve managed to get one. He was kind enough to send me some photos of his prize.
