Air14, also named 100 years Swiss Air Force was an international air show held by the Swiss Air Force in late August and early September 2014 at Payerne Air Base, Switzerland. It claimed to be the biggest airshow in Europe of 2014.
Until 1991, when Switzerland celebrated its 700th formation jubilee, most Swiss airshows had been organized by civilians. Prior to that year, the Swiss Air Force participated in various military and civilian events only. There were no regular airshows organized by the military except one yearly open day at Dubendorf during the Air Force Flight Competitions (Armeeflugmeisterschaften) and small partly public open doors designated to airmen family members in the militia of Switzerland's recruits training. Notable demonstrations were held in 1974 at Dubendorf, Payerne and Locarno, commemorating 50 years of military flying, attracting 100,000 people at Dubendorf. Private organizers also introduced foreign military aircraft, such as the Harrier during the Flying Days in Bex and several airshows at Sion airport 1982, 1986, 1989 and 1997.
After the end of the cold war, invitations were sent to Eastern bloc countries for and during the first airshow in Payerne held 1991, on the occasion of 700 years of Switzerland and 50 years of Ueberwachungsgeschwader (Surveillance Squadron), where Mi-24 helicopters were flown at the show as well as the U.S. Thunderbirds. During Air94 on 26 and 27 August 1994, Patrouille Suisse celebrated its 30th anniversary using the Hunter jet. At the peak of this event, a formation flight of 40 Hunters marked its withdrawal from service.
