Air traffic control
The Royal Air Force withdrew in 1994, at which point the English Electric Lightning acting as a gate guardian was scrapped; only the nose section was retained and sent to the Malta Aviation Museum. Air traffic control services remained, although the section responsible for airspace outside London moved to Swanwick in Hampshire in 2002. The remaining operation was named the London Terminal Control Centre. RAF personnel remained on the site, as military air traffic control functions for the eastern side of England remained. In November 2007, the remaining civil air traffic control services moved to Swanwick, and in January 2008 the military operation also left the site. National Air Traffic Services vacated the site in 2008. The MT section of the Queen's Colour Squadron relocated to RAF Northolt.
