The Lightning was a Cold War Era supersonic fighter aircraft. It was designed and built by English Electric (now absorbed into BAE). The Lightning was the only all-British Mach 2 fighter aircraft and in its almost 30 year service (1960-88) with the RAF it is credited with only a single kill. In 1972 a Lightning shot down a British Harrier whose pilot had ejected due to engine failure. The Harrier was heading into East Germany so was brought down to avoid a diplomatic incident.
