Supersonic flight refers to the movement of an object through the air at speeds greater than the speed of sound, which is approximately 343 meters per second (1,125 feet per second) at sea level. In aviation, this is known as flying at speeds above Mach 1. Supersonic flight introduces unique aerodynamic challenges, such as shock waves and increased drag, which require specialized aircraft design and materials. While not directly a cybersecurity term, supersonic flight is relevant to cybersecurity in the context of secure communication and navigation systems for high-speed military and research aircraft.
