On 10 June, the F-35B Joint Strike Fighter short takeoff/vertical landing variant flew faster than the speed of sound for the first time. U.S. Marine Corps pilot Lt. Col. Matt Kelly climbed to 30,000 feet and accelerated to Mach 1.07 (727 miles per hour) in the off-shore supersonic test track near NAS Patuxent River. It was the first in a series of planned supersonic test flights, and was the aircraft’s 30th test flight overall.
