Image of prototype XB-1 caught breaking the sound barrier
NASA has released a new image providing photographic evidence of Boom Supersonic's XB-1 prototype aircraft breaking the sound barrier. Captured on the second supersonic flight, it used a special imaging technique to record the historic event.
Pretty soon, you end up with the old joke that in order to fake the Moon landing you still had to build and launch the giant rocket, so the only money the alleged fraud saved was the catering bill. In the case of Boom achieving the first commercial supersonic flights, the company teamed up with NASA to capture images of the aircraft blasting past Mach 1 using a technique called Schlieren optics. It can also be used to look at helicopter rotors or propeller blades, analyze vortex patterns on wings, and record how aircraft flying in formation disturb one another by mixing air streams.
