David Doyle AD and A-1 Skyraider

Design work on the Skyraider began at the behest of the US Navy late in WWII. Production began in 1946, and the type made its combat debut in the hands of naval aviators during the Korean War. In the following years, the rugged airframe and powerful engine meant that the type could be adapted into ever-expanding roles of attack, reconnaissance, weather, and electronic-countermeasure types. Though regarded by many as obsolete, in Vietnam the Skyraider again saw combat, now in the hands of not only US Navy and Marine pilots, but also USAF and Republic of Vietnam airmen. Capable of flying low and slow while armed with a massive array of ordnance, the Skyraider not only took on the role of attack aircraft but was also used as air cover for troops on the ground. Its impressive payload earned it the nickname of the "flying dump truck," while its reliance on a massive radial engine in an otherwise jet age caused others to refer to the Skyraider as the "Spad," in homage to the WWI fighter.
