In January 2022, Boom began conducting engine run-ups using the XB-1, in preparation for taxi tests and the first flight later in 2022. [19] In May 2022, ground testing was completed with engine run up done on all three engines. Undercarriage and flight systems were tested and deemed ready. Taxi runs and actual flight runs were expected in late ...
Therefore, for a boom to reach the ground, the aircraft's speed relative to the ground must be greater than the speed of sound at the ground. For example, the speed of sound at 30,000 feet (9,100 m) is about 670 miles per hour (1,080 km/h), but an aircraft must travel at least 750 miles per hour (1,210 km/h) (Mach 1.12) for a boom to be heard ...
A sonic boom is the sound associated with the shock waves created whenever an object traveling through the air travels faster than the speed of sound. Sonic booms generate significant amounts of sound energy, sounding similar to an explosion or a thunderclap to the human ear. The crack of a supersonic bullet passing overhead or the crack of a ...

In March 2016, Boom Technology revealed that it is in the development phases of building a 40-passenger supersonic jet capable of flying Mach 1.7, claiming that the design simulation shows that it will be quieter and 30% more efficient than the Concorde and will be able to fly Los Angeles to Sydney in 6 hours. It is planned to go into service ...

In 1983 Richard Noble had broken the world land speed record with his earlier car Thrust2, which reached a speed of 1,019 km/h (633 mph). The date of Andy Green's record came exactly a half century and one day after Chuck Yeager broke the sound barrier in Earth's atmosphere, with the Bell X-1 research rocket plane on 14 October 1947.
The Forward boom state was 5.9 feet (1.8 m) long and had the smallest diameter of the three, while the Mid-Boom State was 4.3 feet (1.3 m) long and the second largest in diameter. [3] The spike, made of composite materials , creates three small shock waves that travel parallel to each other all the way to the ground, producing less noise than ...
