The interaction of shock waves from two supersonic aircraft, photographed for the first time by NASA using the Schlieren method in 2019. A supersonic aircraft is an aircraft capable of supersonic flight, that is, flying faster than the speed of sound (Mach 1). Supersonic aircraft were developed in the second half of the twentieth century.
It achieved 30 mph (48 km/h) during its first flight, a record by the only plane of controlled take-off and landing in existence. The Bleriot XI then reached 47 mph (76 km/h) in 1909. Fabric-covered biplanes of the World War I era and shortly after could reach 200 mph (320 km/h).
Prior to the Second World War, conventional wisdom throughout the majority of the aviation industry was that manned flight at supersonic speeds was next to impossible, mainly due to the apparently insurmountable issue of compressibility. [2]

The destroyed Valkyrie had logged just 46 flights, and the remaining one ended its career after 83 flights — many of which with NASA as a supersonic testbed — and just over 160 hours in the air.
A United States Navy F/A-18F Super Hornet in transonic flight U.S. Navy F/A-18 approaching the speed of sound. The white cloud forms as a result of the supersonic expansion fans dropping the air temperature below the dew point. [1] [2] Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1).
These movies only scratch the surface of the countless number made about the momentous event, but remind us of the horrors and sacrifices made during the devastating global conflict. 20.
