Pictured is the SHOOTING STAR leaving behind a trail of smoke on a special test for the Air Technical Service Command at Van Nuys Metropolitan Airport. In addition to the 4000 Ibs. of thrust developed by the General Electric I-40 jet turbine engine, the two Jato rocket-assist units develop a total of 2000 Ibs. of thrust for 12 to 15 seconds. In a lightly loaded SHOOTING STAR with the Jato units, take-off was made in 1185 ft., about 40 per cent of the normal take-off run. The Jato units. made by Aerojet Engineering Co .. Cal.. may be jettisoned at any time after they are fired, and cartridges may be refilled even after jettisoning, operated by a trigger on the control stick.
