The TIE fighter is the signature starfighter of the Galactic Empire in Star Wars, first heard in the original 1977 film as Imperial pilots hunted Rebel ships. Its thin, screaming engine note was designed to sound fast and threatening, unlike the deeper roar of other spacecraft, and it quickly became one of the franchise's most recognisable audio cues. As Star Wars clips spread online, the flyby was reused as shorthand for a sudden arrival, a villainous entrance or a high-speed pass. It remains popular because a single second instantly tells viewers the Empire is coming.
