High Altitude Helo


Recommended Posts

10 February 1947: At Patterson Field, Dayton, Ohio, Major Ernest Murray Cassell, Jr., Air Corps, United States Army, flew a Sikorsky YR-5A helicopter, serial number 43-46628, to an altitude of 5,842 meters (19,167 feet), setting a Fédération Aéronautique Internationale (FAI) World Altitude Record for helicopters.

Major Cassell took off from Patterson Field at 11:05 a.m., and landed at 12:02 p.m. He said that he knew the helicopter had reached its absolute ceiling. “She just wouldn’t go any higher. At the peak I dived to pick up speed, pulled up and the ship just quivered in a tip-stall as if to say, ‘That’s all I can do.’ ”

Always Aviate, then Navigate, then Communicate. And never be low on Fuel, Altitude, Airspeed, or Ideas.
