The world record loop is the record for the highest number of aircraft to successfully complete an aerobatic loop while flying in formation. The current record is 22 aircraft. The record was set by the Royal Air Force aerobatic team, the Black Arrows, who successfully looped 22 Hawker Hunter jet aircraft every day of the September 1958 Society of British Aerospace Companies Farnborough Airshow, beating the previous record set by the Pakistan Air Force, who looped the 16 North American F-86 Sabres in February 1958. The record required the team to train pilots from other RAF squadrons. The team initially wanted to loop 20 aircraft, but additional aircraft were added to the formation in order to improve the formation's aesthetic appearance.
