Although Concorde and the Tu-144 were the first aircraft to carry commercial passengers at supersonic speeds, they were not the first or only commercial airliners to break the sound barrier. On 21 August 1961, a Douglas DC-8 broke the sound barrier at Mach 1.012, or 1,240 km/h (776.2 mph), while in a controlled dive through 41,088 feet (12,510 m).
Through the NACA program, he became the first human to officially break the sound barrier on October 14, 1947, when he flew the experimental Bell X-1 at Mach 1 at an altitude of 45,000 ft (13,700 m), for which he won both the Collier and Mackay trophies in 1948. He then went on to break several other speed and altitude records in the following ...
The first aircraft to break the sound barrier with a female pilot was an F-86 Canadair Sabre with Jacqueline Cochran at the controls. [1] According to David Masters, [ 2 ] the DFS 346 prototype captured in Germany by the Soviets, after being released from a B-29 at 32800 ft (10000 m), reached 683 mph (1100 km/h) late in 1951, which would have ...
At a speed of about 767 miles per hour, depending on temperature and humidity, a moving object will break the sound barrier. It was not until World War II, when aircraft started to reach the ...
On August 21, 1961, a DC-8 broke the sound barrier at Mach 1.012 (660 mph/1,062 km/h) while in a controlled dive through 41,000 feet (12,497 m) and maintained that speed for 16 seconds. The flight was to collect data on a new leading edge design for the wing, and, while doing so, the DC-8 became the first civilian jet – and the first jet ...
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 ...
Reaction Motors, Inc. (RMI) was an early American maker of liquid-fueled rocket engines, located in New Jersey.RMI engines with 6,000 lbf (27 kN) thrust powered the Bell X-1 rocket aircraft that first broke the sound barrier in 1947, and later aircraft such the X-1A, X-1E, and the Douglas D-558-2 Skyrocket.
Sir Richard Branson's Virgin Galactic made history Monday, announcing that its SpaceShipTwo (SS2) space vehicle has successfully completed its first supersonic, rocket-powered test flight. At 7:02 ...
