Bicester Aerodrome, formerly RAF Bicester, is an airfield on the outskirts of the English town of Bicester in Oxfordshire.
 Dating back to 1916, this military airfield is notable as the location of the first flight of the prototype Handley Page Halifax in 1939 and was later the home of No. 71 Maintenance Unit, RAF (Royal Air Force); the RAF finally left in 2004.
The Battle of the Heligoland Bight was the first "named" air battle of the Second World War, which began the longest air campaign of the war, the Defence of the Reich.
 On 3 September 1939, the United Kingdom declared war on Nazi Germany after the German invasion of Poland, which started the European War.
 The British did not assist Poland by land or sea, but over the ensuing weeks, RAF Bomber Command flew several missions against German targets.
 A number of these air raids were directed at "Kriegsmarine" (German Navy) warships in German ports to prevent their use in the Battle of the Atlantic.
 With the front lines static between September 1939 and May 1940, a period known as the "Phoney War" set in, with little fighting on land or in the air.
 However, at sea, German U-boat (submarine) forces were taking a considerable toll on Allied shipping.
 The Air Ministry decided to launch an attack on German surface ships to prevent them supporting the U-boats in the North Atlantic.
 On 18 December 1939, a force of three RAF bomber squadrons were sent to engage German ships in the Heligoland Bight and sink or damage as many as possible.
 Originally 24 Vickers Wellingtons took off.
 Two turned back owing to engine trouble before reaching German airspace.
 The German reaction was slow.
 Eventually they scrambled strong fighter aircraft forces to intercept.
 Just over 120 aircraft, 80–100 German and 22 British, were involved but only 44 German fighters made contact with the British bombers.
The Handley Page Halifax was a British Royal Air Force (RAF) four-engined heavy bomber of the Second World War.
 It was developed by Handley Page to the same specification as the contemporary of the Avro Lancaster, and the Short Stirling, all three aircraft being four-engined heavy bombers.
The aircrews of RAF Bomber Command during World War II operated a fleet of bomber aircraft carried strategic bombing operations from September 1939 to May 1945, on behalf of the Allied powers.
 The crews were men from the United Kingdom, other Commonwealth countries, and occupied Europe, especially Poland, France, Czechoslovakia and Norway, as well as other foreign volunteers.
 While the majority of Bomber Command personnel were members of the RAF, many belonged to other air forces – especially the Royal Canadian Air Force (RCAF), Royal Australian Air Force (RAAF) and Royal New Zealand Air Force (RNZAF).
 Under Article XV of the 1939 Air Training Agreement, squadrons belonging officially to the RCAF, RAAF, and RNZAF were formed, equipped and financed by the RAF, for service in Europe.
 While it was intended that RCAF, RAAF, and RNZAF personnel would serve only with their respective "Article XV squadrons", in practice many were posted to units of the RAF or other air forces.
 Likewise many RAF personnel served in Article XV squadrons.
In its early years, the British V bomber force relied on the concept of aircraft dispersal to escape the effects of an enemy attack on their main bases.
 There were 26 such bases in the late 1950s, in addition to the ten main bases – RAF Coningsby, RAF Cottesmore, RAF Finningley, RAF Gaydon, RAF Honington, RAF Marham, RAF Scampton, RAF Waddington, RAF Wittering (HQ RAF Bomber Command) and RAF Wyton – a total of 36 bases available for the V bomber force.
No. 304 (Land of Silesia) Polish Bomber Squadron (Polish: "304 Dywizjon Bombowy "Ziemi Śląskiej im.
 Ks.
 Józefa Poniatowskiego"" ) was a Polish World War II bomber unit.
 It fought alongside the Royal Air Force under their operational Command and operated from airbases in the United Kingdom, serving from April 1941 as a bomber unit in RAF Bomber Command, from May 1942 as an anti-submarine unit in RAF Coastal Command and from June 1945 as a transport unit in RAF Transport Command.
Windrushers Gliding Club is a gliding club flying from Bicester Airfield in Oxfordshire, where it moved to from Little Rissington in 1956, later merging with the Royal Air Force Gliding & Soaring Association.
The club was reformed as a separate entity in July 2004 after the RAFGSA moved to RAF Halton.
Within a year of reforming, it hosted the UK Junior National Championship and its own Regional championship.
RAF Holme-on-Spalding Moor, or more simply RAF Holme as it was also known, was an airfield in Yorkshire.
 Built during the Second World War, it was used during the war by the Royal Air Force (RAF) as a bomber station, and after the war as a transport airfield and bomb store before being "mothballed".
 In the 1950s, the RAF used the station as a training camp before it was transferred to the United States Air Force (USAF) as a reserve station during the Cold War.
 After USAF use, it became a testing airfield for Blackburn Aircraft and its successor British Aerospace until 1983, when the airfield was closed.
 Many of the airfield buildings survive as an industrial estate, but most of the runways have been demolished.
Marshal of the Royal Air Force Sir Edward Leonard Ellington, {'1': ", '2': ", '3': ", '4': "} (30 December 1877 – 13 June 1967) was a senior officer in the Royal Air Force.
 He served in the First World War as a staff officer and then as Director-General of Military Aeronautics and subsequently as Controller-General of Equipment.
 In the inter-war years he held command positions in the Middle East, in India and then in Iraq.
 He served as Chief of the Air Staff in the mid-1930s and in that role he implemented a plan, known as 'Scheme F', to increase the size of the Royal Air Force to 187 squadrons (five bomber squadrons for every two fighter squadrons reflecting the dominance of the bomber strategy at the time) within three years to counter the threat from Hitler's Germany.
 He also broke up the command known as "Air Defence of Great Britain" to create RAF Fighter Command, RAF Bomber Command, RAF Coastal Command and RAF Training Command.
 He then served as Inspector-General of the RAF until his retirement in 1940.
RAF Tholthorpe was a Royal Air Force air station operated by RAF Bomber Command during the Second World War.
 The station, which had been opened in the late 1930s as a grass airfield, was located near Easingwold, North Yorkshire, UK.
 Tholthorpe airfield operated as a sub-station of RAF Linton-on-Ouse.
