Supersonic jet flyby sounds have long been a staple of film, television and video game sound design, used whenever a scene needs instant speed and power without showing an aircraft in detail. The distinctive crack of a sonic boom, caused when an aircraft breaks the sound barrier, makes the effect instantly recognisable even to listeners who have never heard a real jet. Online, creators now use short jet clips like this one as transitions, punchlines and reaction sounds, dropping them into edits, gaming videos and memes to exaggerate movement, surprise or a sudden exit.
