The USAF Air Demonstration Squadron is the air demonstration squadron of the United States Air Force. The Thunderbirds, as they are colloquially known, are assigned to the 57th Wing, and are based at Nellis Air Force Base, Nevada. Created in 1953, the USAF Thunderbirds are the third-oldest formal flying aerobatic team (under the same name) in the world, after the French Air Force Patrouille de France formed in 1931 and the United States Navy Blue Angels formed in 1946.

The Thunderbirds Squadron tours the United States and much of the world, performing aerobatic formation and solo flying in specially marked aircraft. The squadron's name is taken from the creature that appears in the mythologies of several indigenous North American cultures.

Overview

The Thunderbirds Squadron is a named USAF squadron, meaning it does not carry a numerical designation. It is also one of the oldest squadrons in the Air Force, its origins dating to the organization of the 30th Aero Squadron, formed at Kelly Field, Texas, on 13 June 1917.

Officers serve a two-year assignment with the squadron, while enlisted personnel serve three to four years. Because the squadron performs no more than 88 air demonstrations each year, replacements must be trained for about half of the team each year, in order to provide a constant mix of experience. In addition to their air demonstration responsibilities, the Thunderbirds are part of the USAF combat force and if required, can be rapidly integrated into an operational fighter unit. Since 15 February 1974 the Thunderbirds have been a component of the 57th Wing at Nellis AFB. Since 1953, they have flown in front of more than 300 million people.

F-16 Fighting Falcon

The Thunderbirds perform aerial demonstrations in the F-16C Fighting Falcon, and they also fly two F-16D twin-seat trainers.

The F-16 has been the demonstration aircraft for the Thunderbirds since the 1983 season. In January 1982, four members of the squadron were killed in what became known as the "Diamond Crash" of T-38 Talon aircraft which the squadron had flown since 1974. Partially as a result of that accident, the squadron switched to the F-16A, and sat out the 1982 airshow season and spent that year retraining and transitioning over to the new aircraft to ready themselves for the 1983 season. The F-16, however, had been considered for transition prior to the accident. In rebuilding the Thunderbird Team, the Air Force recruited previous Thunderbird pilots, qualified each in the F-16A, and had them begin by flying "two-ship" maneuvers, then expanded the program one airplane at a time up to the full six airplanes. Beginning in June 1982, the F-16 Thunderbirds were led by Major Jim Latham.

The team continues to fly the F-16, having switched from the F-16A to the F-16C in 1992.

During its operational history, the 30th served in World War I as a training unit in France, its mission to train fighter pilots to go into combat on the Western Front. The squadron was almost torpedoed on its troop ship crossing the Atlantic Ocean. Stationed at Clark Field in the Philippines on 7 December 1941, it was almost wiped out in the 1941 Battle of the Philippines. Some members of the squadron fought as an infantry unit and were captured by the Japanese, being subjected to the Bataan Death March. The squadron was withdrawn to Australia, being reformed and later attacked Japan as a B-29 Superfortress squadron in 1945. It was awarded nine Presidential Unit Citations in World War II. During the Korean War, the 30th attacked North Korean targets with B-29's.

Present-day USAF Thunderbirds carry the lineage, history, and honors of the 30th on active duty.

The team had flown 26 shows by that August. The first team leader was Major Richard C. Catledge (1953–1954), and the first plane used by the unit was the straight-wing F-84G Thunderjet. Because the Thunderjet was a single-seat fighter, a two-seat T-33 Shooting Star served as the narrator's aircraft and was used as the VIP/Press ride aircraft. The T-33 served with the Thunderbirds in this capacity in the 1950s and 1960s.

The next year the Thunderbirds performed their first overseas air shows, in a tour of South and Central America, and added a permanent solo routine to the demonstration. In the spring of 1955, under their second commander/leader (September 1954 – February 1957), Captain Jacksel M. Broughton, they moved to the swept-wing F-84F Thunderstreak aircraft, in which they performed 91 air shows, and received their first assigned support aircraft, a C-119 Flying Boxcar.

This practice remained in force through the 1973 season. In 1961, the team was compelled to discontinue the vertical bank maneuver due to an FAA regulation prohibiting aerobatics that pointed the nose of the aircraft toward the crowd. The year 1962 saw the introduction of dual solo routines, and the Thunderbirds went on their first European deployment in 1963, the year after the disbanding of the (see below). The team switched to the F-105 Thunderchief for the 1964 season, but were forced to re-equip with the F-100D after only six airshows due to a catastrophic structural failure of the No. 2 aircraft during a pitch-up maneuver that resulted in the death of Capt Gene Devlin at Hamilton Air Force Base on 9 May. The F-100D Super Sabre was retained through the 1968 season.

F-4 Phantom II era

By 1967, the Thunderbirds had flown 1,000 shows. In 1969, the squadron re-equipped with the front-line F-4E Phantom, which it flew until 1973, the only time the Thunderbirds would fly jets similar to those of the Navy's Blue Angels as it was the standard fighter for both services in the 1960s and 1970s.

T-38 Talon era

The team flew only six air shows in 1973 and was grounded for some time. Due to the 1973 oil crisis<!-- October-->, they switched to the more economical T-38 Talon for the 1974 season, as five T-38s used the same amount of fuel as one F-4 Phantom. The switch<!-- to the T-38 also--> saw an alteration of the flight routine to exhibit the aircraft's maneuverability in tight turns, and <!--also--> ended the era of the black tail on the No. 4 slot plane, now regularly cleaned and shined like the others.

In 1982, the Thunderbirds suffered a catastrophic loss during pre-season training on
