The Thunderbirds, the US Air Force Air Demonstration Squadron, performed the team’s 2,000th official demonstration in the F-16 Fighting Falcon at an airshow at Columbus AFB, Mississippi, on 6 April 2014. The Thunderbirds, based at Nellis AFB, Nevada, transitioned to the Block 15 F-16A in August 1982. The team began flying the Block 32 F-16C in 1992 and converted to the Pratt & Whitney F100-PW-229-powered Block 52 F-16C for the 2009 show season. The Thunderbirds, which date back to 1953, have flown the Fighting Falcon for more than half of its history.
