full_context: Document 1: Bournemouth Aviation Museum: The Bournemouth Aviation Museum is an aviation museum located next to Bournemouth International Airport, near the village of Hurn in Christchurch. It houses a number of aircraft, aero engines, cockpits and a double-decker bus. Unusually for such a museum, its policy is to have open cockpits and visitors are encouraged to climb into the cockpits and press knobs, turn dials, pull levers, flick switches, etc. Cockpits open in this manner include the Vulcan, Lightning and Canberra. It has a flight simulator which is free to use, operated from a mock up cockpit. The museum has recently restored a Boeing 737-200 named 'The Spirit of Peter Bath' and has created an exhibition about Sir Peter Bath and his company 'Bath Travel' inside the fuselage. It is believed that Bournemouth Aviation Museum is the only museum in Europe to include a 737-200 in its collection. Even more recently the museum has taken ownership of the forward fuselage of an ex Empire Test Pilots School BAC 1-11, quite apt considering the aircraft was built only a few hundred metres from where it rests now.

Document 9: Junkers Ju 88: The Junkers Ju 88 was a German World War II "Luftwaffe" twin-engined multirole combat aircraft. Junkers Flugzeug- und Motorenwerke (JFM) designed the plane in the mid-1930s as a so-called "Schnellbomber" (fast bomber) that would be too fast for fighters of its era to intercept. It suffered from a number of technical problems during its development and early operational periods but became one of the most versatile combat aircraft of the war. Like a number of other "Luftwaffe" bombers, it served as a bomber, dive bomber, night fighter, torpedo bomber, reconnaissance aircraft, heavy fighter and at the end of the war, as a flying bomb.

Document 11: List of surviving Boeing B-17 Flying Fortresses: The Boeing B-17 Flying Fortress is a four-engine heavy bomber aircraft primarily employed by the United States Army Air Forces (USAAF) during World War II. Developed by Boeing, a total of 12,731 aircraft had been produced by Boeing, Douglas and Lockheed from 1936 until 1945. Over 8,000 were lost in either combat operations or training accidents. The remaining combat veterans and early production models were stored and later scrapped in the vast scrap drives of the late 1940s, many going to aircraft boneyards like Davis-Monthan Air Force Base in Tucson, Arizona, the largest of its kind within the United States' borders.
Document 12: Boeing XF8B: The Boeing XF8B (Model 400) was a single-engine aircraft developed by Boeing during World War II to provide the United States Navy a long-range shipboard fighter aircraft. The XF8B was intended for operation against the Japanese home islands from aircraft carriers outside the range of Japanese land-based aircraft. Designed for various roles including interceptor, long-range escort fighter, dive-bomber, and torpedo bomber, the final design embodied a number of innovative features in order to accomplish the various roles. Despite its formidable capabilities, the XF8B-1 was fated never to enter series production.

Document 14: North American P-51 Mustang: The North American Aviation P-51 Mustang is an American long-range, single-seat fighter and fighter-bomber used during World War II and the Korean War, among other conflicts. The Mustang was designed in 1940 by North American Aviation (NAA) in response to a requirement of the British Purchasing Commission. The Purchasing Commission approached North American Aviation to build Curtiss P-40 fighters under license for the Royal Air Force (RAF). Rather than build an old design from another company, North American Aviation proposed the design and production of a more modern fighter. The prototype NA-73X airframe was rolled out on 9 September 1940, 102 days after the contract was signed, and first flew on 26 October.
Document 15: Boeing B-17 Flying Fortress: The Boeing B-17 Flying Fortress is a four-engine heavy bomber developed in the 1930s for the United States Army Air Corps (USAAC). Competing against Douglas and Martin for a contract to build 200 bombers, the Boeing entry (prototype Model 299/XB-17) outperformed both competitors and exceeded the air corps' performance specifications. Although Boeing lost the contract (to the Douglas B-18 Bolo) because the prototype crashed, the air corps ordered 13 more B-17s for further evaluation. From its introduction in 1938, the B-17 Flying Fortress evolved through numerous design advances, becoming the third-most produced bomber of all time, behind the B-24 and the multirole Ju 88.
