👉 Hypervelocity, also known as high velocity or supersonic flight, refers to a state of flight where an aircraft reaches speeds exceeding the speed of sound. This is achieved through propulsive systems that generate extremely high velocities and accelerations in order to reach a significant altitude without the need for engines. The term "hypervelocity" was coined by aviation enthusiasts and researchers due to the rapid acceleration experienced during supersonic flights, which can be described as an "unpredictable acceleration of Mach
