The F-16 Fighting Falcon is a single engine multirole fighter aircraft originally developed by General Dynamics for the United States Air Force and introduced in 1978. Flown by air forces around the world, it became one of the most recognisable modern jets at airshows and in news footage. Recordings of its engine roar and flybys circulate online as stock effects, where editors reuse them for other aircraft too because the rising turbine sound instantly signals a fast military jet passing overhead.
