The Battle of Britain Memorial Flight (BBMF) is an aerial display team flying historic aircraft. They appear at shows throughout the country, state occasions and at events commemorating the Second World War. The aircraft normally flown are an Avro Lancaster, a Supermarine Spitfire and a Hawker Hurricane. The flight is administratively part of No. 1 Group RAF, flying out of RAF Coningsby in Lincolnshire. It is possible to see the aircraft at a visitor centre at Coningsby, though it is recommended you check which ones can be seen before making a special trip.
IWM Duxford is a historic RAF airfield also used by the United States Army Air Forces during the Second World War. It houses the Imperial War Museum's huge collection of historic aircraft and other large vehicles like tanks. Permanent exhibitions include the American Air Museum, Battle of Britain, Land Warfare and Historic Duxford (many of the buildings are original). You can get up close and personal with some of the most famous aircraft ever, including the Spitfire, Lancaster, Concorde and Vulcan. It's probably the best aviation collection and museum in the country, and enormous, so allow enough time. Air Shows are a regular feature and Duxford is also home to the Airborne Assault and Royal Anglian Museums.
The Fleet Air Arm Museum tells the story of the Royal Navy in the air. There are over 90 aircraft, from biplanes to supersonic jets, plus thousands of other artefacts, on show in four exhibition halls. It is Europe's largest naval aviation Museum. In addition it houses the first British Concorde, which you can go on board, and the 'Aircraft Carrier Experience', a fascinating tour round a realistic mocked-up carrier. The museum is exceptionally well laid out.
One of two RAF museums in Britain (the other one is in Hendon, north London), RAF Cosford displays 70+ aircraft, including the world's oldest Spitfire, with exhibits shown in three historic hangers. On site is the National Cold War Exhibition, which tells the story of this uncertain period in our history and where you can see all three of Britain's V-Bombers - the Vulcan, Victor and Valiant.
The Royal Air Force Museum is on the site of the historic Hendon aerodrome, just over 30 minutes from central London. If you like aircraft, you will love it. There are entire hangers dedicated to WW1 aircraft, bombers of all sorts and the Battle of Britain, plus a lot more besides - including flight simulators. Be awed by the Avro Vulcan or Lancaster, or wonder how the flimsy aircraft of the early days managed to stay up.
There is a sister museum in Cosford, Shropshire.
A military museum located on a corner of the historic Tangmere RAF station, which was on the front line during the Battle of Britain. It also provided the forward take-off point for Lysander aircraft, based at RAF Tempsford in Bedfordshire, to refuel before landing agents in enemy-occupied Europe. The museum was opened by enthusiasts in 1982, owns a number of historic and replica aircraft and includes flight simulators and several permanent exhibitions.
