From a press release:
A rare Cold War jet fighter will perform its first flying display in the UK for almost a decade when it appears at next summer's Royal International Air Tattoo at RAF Fairford in Gloucestershire.
The Romanian Air Force (RoAF) has agreed to send two MiG-21 'Lancers' to the Cotswolds: one for static display and the other to take part in the flying display. It also plans to send its latest support aircraft - the C-27 Spartan - to the airshow on July 17-18.
The 'Lancer' fleet constitutes the backbone of the Romanian Air Force, performing air defence, close air support and training roles. Whilst the aircraft has more recently participated successfully in various NATO exercises, during the Cold War, it was one of the Eastern Bloc fighters feared most by the West.
Earlier variants took part in the Vietnam War, the Middle East conflicts of the 1960s-1980s, the Indo-Pakistani wars of 1965 and 1971, the Angolan Civil War and the Balkans War of the 1990s. The Romanians are due to replace the aircraft in 2012.
