Microsoft Flight Simulator 5.1: The Virtual Squadron (1996)

The Virtual Squadron: Thunderbirds Past, Present and Future! is an unofficial add-on for Microsoft Flight Simulator 5.X. It gives the player all the aircraft flown by the US Thunderbirds air demonstration squadron at the time of its release, together with their USAF equivalents, and a host of bonus aircraft. At the time this add-on was released the F-22 Lightning was not in service as congressional funding was needed before it could go into production and be deployed, hence the 'Future' element in the title.
