Compared to the all-moving tail on the M.52 the X-1 used a conventional tail with elevators but with a movable stabilizer to maintain control passing through the sound barrier. It was in the X-1 that Chuck Yeager became the first person to break the sound barrier in level flight on 14 October 1947, flying at an altitude of 45,000 ft (13.7 km).
Boom Supersonic’s XB-1 aircraft climbed over 35,000ft on Tuesday before accelerating to Mach 1.1 speed and then breaking the sound barrier in three high-speed runs spanning 35 minutes over the ...
Boom Supersonic’s XB-1 aircraft broke the sound barrier for the first time ever on Tuesday, ushering in a new era of supersonic flight. The jet exceeded Mach 1 after taking off from the Mojave ...
The sound barrier was first broken on Oct. 14, 1947, according to the U.S. Air Force. That's when Capt. Chuck Yeager and the Bell X-1 rocket-propelled aircraft broke the sound barrier.
This is the first time in history that a land vehicle has exceeded the speed of sound. The new records are as follows: Flying mile 1,227.985 km/h (763.035 mph) Flying kilometre 1,223.657 km/h (760.345 mph) In setting the record, the sound barrier was broken in both the north and south runs. Paris, 11 November 1997.
In the late 1950s, following the breaking of the sound barrier, first by experimental aircraft, then military aircraft, a supersonic passenger aircraft was thought feasible. By the early 1970s however, opposition led to bans on commercial supersonic flight in Sweden, Norway, the Netherlands, West Germany, Switzerland, Ireland, Canada and the ...
After getting to altitude, Brandenburg opened up the test plane's throttles, accelerating to Mach 1.1, or about 845 mph (1,360 kph) -- faster than the speed at which sound travels.
Herbert Henry Hoover (May 18, 1912 – August 14, 1952) [1] was an American NACA experimental test pilot who, on March 10, 1948, became the first civilian and second person to break the sound barrier, [2] a feat for which he was awarded the Air Medal "for meritorious achievement while participating in aerial flight."
