Definition of supersonic and hypersonic flight

Supersonic and hypersonic flight refer to the ability of an aircraft or object to travel at speeds exceeding the speed of sound (Mach 1) and several times the speed of sound, respectively. Supersonic flight typically involves speeds ranging from Mach 1 to Mach 5, while hypersonic flight encompasses speeds greater than Mach 5. At supersonic speeds, shockwaves are created as the aircraft moves faster than the speed at which sound waves propagate, resulting in a characteristic sonic boom.
