Biggin Hill Heritage Hangar Announces Latest Spitfire Under Restoration Biggin Hill Heritage Hangar Announces Latest Spitfire Under Restoration Images copyright Peter Arnold Collection As we have reported in the past, the Biggin Hill Heritage Hangar and its parent organization, The Spitfire Company (Biggin Hill) Ltd, have made remarkable progress in their work restoring Supermarine Spitfires at their facility on London Biggin Hill Airport, south east of London, England. This site is steeped in Spitfire history, being the former home of what once was RAF Biggin Hill, a major fighter base during the Battle of Britain. The company has worked on a dozen or so Spitfires since their inception, and has several on site at any given time, both airworthy and those under rebuild. Readers might recall the first flight last year of ‘The Greek Spitfire’, Spitfire Mk.IX MJ755, which is the last complete surviving example to have served in the Greek Air Force.
