The American Navy's twin turbine 'Sikorsky HSS-2' helicopter claims a new world helicopter speed record of 192.9 miles per hour. Fastest speed previously flown was 166.5 miles an hour by the Russian MIL-6, on November 21, 1959. The Russian record was set over a 100 kilometre (62 miles) closed circuit.
This new record was set at 7:00 p.m. May 18 over a three kilometre (1.86 miles) straight line course at Bradley Field, in Windsor Locks, Connecticut. The speed runs were conducted under the sanction of the National Aeronautics Association. Certification by the Federation Aeronautics Internationale, Paris, France, is required before the record becomes official. NAA is the United States representative of the F.A.I.
America's big turbocopter is powered by two General Electric T-58-8 gas turbine engines of 1,250 shaft horsepower each.
Commander Patrick L. Sullivan, USN, Pilot, and Lt. Veverly W. Witherspoon, USN, Co-pilot, flew the HSS-2 on its speed runs.
