Air Force Museum
De Havilland DH 98 Mosquito
The famous British Mosquito – known to many as "Mossie" – was a versatile aircraft used extensively during World War II. Constructed primarily of plywood with a balsa wood core, it had excellent speed, altitude and range. First flown on November 25, 1940, the Mosquito entered production in mid-1941 and was produced until well after the end of the war.

History & service
The famous British Mosquito – known to many as "Mossie" – was a versatile aircraft used extensively during World War II. Constructed primarily of plywood with a balsa wood core, it had excellent speed, altitude and range. First flown on November 25, 1940, the Mosquito entered production in mid-1941 and was produced until well after the end of the war. Almost 8,000 Mossies were built in Great Britain, Canada, and Australia.
Although best known for its service with the Royal Air Force, the Mosquito flew in several US Army Air Force units as a photographic and weather reconnaissance aircraft, and as a night fighter. During the war, the USAAF acquired 40 Canadian Mossies and flew them under the American F-8 (photo reconnaissance) designation. In addition, the British turned over more than 100 Mosquitoes to the USAAF under Reverse Lend-Lease. These aircraft retained their British designations.
The aircraft on display is a British-built B. Mk. 35 manufactured in 1946 (later converted for towing targets) and is similar to the P.R. Mk. XVIs used by the USAAF. It was flown to the museum in February 1985. This Mosquito, serial RS709, has been restored to a Mk. XVI configuration and painted as NS519, a weather reconnaissance aircraft of the 653rd Bombardment Squadron based in England in 1944-1945.
Just before D-Day (the June 6, 1944, invasion of France), black and white stripes were applied almost overnight to a vast majority of US and British aircraft to clearly identify them during the Normandy landings. In the rush to mark all the aircraft, masking and spraying sometimes gave way to more expeditious method of painting them by hand.
Invasion stripes, like the ones being applied by the ground crewman in the museum's exhibit, would have completely encircled the wings and fuselage. The 25th Bombardment Group adopted a red tail for their Mosquitoes in August 1944 and removed the invasion stripes from the upper wing and upper fuselage surfaces in September 1944.

Aircraft change the battlefield
In the First World War, aircraft became valuable because they could see beyond the front line. Reconnaissance and artillery observation affected decisions on the ground. Once that information mattered, opposing forces had reason to attack the aircraft gathering it. Fighters, defensive armament, and increasingly specialized missions developed around this contest over observation and freedom of movement.
The aircraft were fragile by later standards, but their crews worked inside a rapidly expanding military system. Training, maintenance, replacement aircraft, photography, communications, and weather reporting supported each sortie. Improvements in engines and armament changed tactics, while the pressures of combat exposed weaknesses that might have taken much longer to discover in peacetime.
Personal stories should be read alongside those systems. A uniform or a named aircraft connects the war to an individual, but the individual depended on many others and operated under constraints that skill could not eliminate. Aircraft from opposing sides show how designers answered similar problems in different ways. The later military collections in Dayton and at Udvar-Hazy reveal what endured: the need to gather information, protect friendly forces, move people and supplies, and coordinate action across distance. The scale changed enormously; the relationship between an aircraft's design and the job it had to perform remained fundamental.
