The de Havilland DH.98 Mosquito was a British twin-engine shoulder-winged multi-role combat aircraft, introduced during the Second World War. It was one of few operational front-line aircraft of the era whose frame was constructed almost entirely of wood. Nicknamed The Wooden Wonder, it was affectionately as the "Mossie" to its crews. The total number of DH98 Mosquito aircraft built was 7,781, the type serving with the main Allied air forces, including both the United States and Russia.

When Mosquito production began in 1941 it was the fastest propeller driven operational aircraft in the world. The first variant was an unarmed, high-speed, high-altitude photo-reconnaissance aircraft. Originally conceived as an unarmed fast bomber, the Mosquito's use evolved during the war into many roles including low to medium-altitude daytime tactical bomber, high-altitude night bomber, pathfinder, day or night fighter, fighter-bomber, intruder, and maritime strike aircraft. It was also used by the British Overseas Airways Corporation (BOAC) as a fast transport to carry small high-value cargoes to, and from, neutral countries, through enemy-controlled airspace. The crew of two, pilot and navigator, sat side by side, but a single passenger could ride in the aircraft's bomb bay when necessary.

The Mosquito FB Mk. VI was often flown in special raids, such as Operation Jericho, an attack on Amiens Prison in early 1944, and precision attacks against military intelligence, security and police facilities (such as Gestapo headquarters). On the 10th anniversary of the Nazi' seizure of power in 1943, a morning Mosquito attack knocked out the main Berlin broadcasting station while Hermann Goering was speaking, putting his speech off the air. Goering later said: "It makes me furious when I see the Mosquito. I turn green and yellow with envy. There is nothing the British do not have. They have the geniuses and we have the nincompoops."

The Mosquito flew with the RCAF and other air forces in the European, Mediterranean and Italian theatres. After the end of the Second World War Spartan Air Services flew 10 ex-RAF Mosquitoes, mostly B.35's plus one of only six PR.35's built, for high-altitude photographic survey work in Canada. There are approximately 30 non-flying Mosquitos around the world with five airworthy examples, three in the United States, one in Canada and one in New Zealand. Harold Skaarup web page and Wikipedia

W 4050

Merlin 21

First prototype Mosquito built in secret at Salisbury Hall near the main DH plant at Hatfield. Flown with "B-Condition" (trade-plate) marking E-0234 for the first two flights. Used by Aeroplane and Armament Experimental Establishment, Boscombe Down; de Havilland and Rolls-Royce. Fuselage cracked on 24 Feb 1941 while taxiing at Boscombe Down due to a faulty tailwheel. It was repaired on site using the fuselage from the 2nd prototype W4051, which in turn received the first production fuselage. W4050 became the primary development airframe throughout the war. Many modifications were tested, some of which included an extended tailplane, lengthened engine nacelles, a variety of engine exhausts, dummy gun turret (for drag testing), extended wings and 4-blade propellers. Fitted with Merlin 61 engines in Oct 1941 and returned to testing in Jun 1942, it reached 40,000 feet on its second flight. Merlin 77 engines were then installed and in Nov 1942, W4050 achieved a true airspeed in level flight of 437 mph (also reported as 439 mph) at 29000 feet, the highest speed ever reached by any Mosquito, and at the time the fastest of any operational Allied aircraft.



W4050 made its last flight in Dec 1943. Shortly after it was sent back to Hatfield to be used for technical training. It was used in the 1945 film "The Mosquito Story" and then sent to Salisbury Hall, which became the de Havilland Aeronautical school. Although destined for scrapping, it was stored surreptitiously by W.J.S. Baird, then de Havilland assistant public relations manager, at a number of locations including Hatfield, Panshanger, and Chester. The new owner of Salisbury Hall, Maj. Walter Goldsmith, learned of the de Havilland connection and raised funds to erect a hangar and have W4050 re-assembled there. On display as of 15 May 1959 at the Mosquito Aircraft Museum, which became the de Havilland Heritage Centre, now called the de Havilland Aircraft Museum. W4050 is said to be the only surviving 2nd World War aircraft prototype in the world. An initial static restoration was done between 2001-2003. A more complete restoration was done between 2011-2015, including one engine running.
