1949Jrnl. Brit. Interplanetary Soc. VIII. 139 A new type ‘high-speed’ parachute, intended for use in retrieving recording equipment from high-altitude rockets, was tested recently... Ordinary parachutes were ripped to shreds after falling free into the denser atmosphere... Expelled from A-4 rockets at altitudes up to 100 miles.., the rotochute attains supersonic velocity before atmospheric density builds up and the blades begin to revolve, gradually being forced out against air pressure to assume a horizontal position. 1955Sci.
