Teledyne Ryan Aeronautical delivered more than 20 composite skin surveillance drones to Egypt in the mid 1980’s. These high subsonic speed aircraft descend to earth under parachute for each landing. The Pioneer provided parachute system first slows the vehicle with an 8.8 ft ribbon drogue that is released after several seconds, and extracts a 76.4 ft diameter triconical main final recovery parachute.
