F-19
F-19 is the designation for a hypothetical US fighter aircraft that has never been officially acknowledged, and has engendered much speculation that it might refer to a type of aircraft whose existence is still classified. History Since the unification of the numbering system in 1962, U.S. fighters have been designated by consecutive numbers, beginning with the F-1 Fury. ''F-13'' was never assigned to a fighter due to triskaidekaphobia, though the designation had previously been used for a reconnaissance version of the B-29. After the F/A-18 Hornet, the next announced aircraft was the YF-20 Tigershark. The USAF proposed the F-19 designation for the fighter, but Northrop requested the "F-20" instead. The USAF finally approved the F-20 designation in 1982.Frey, Lieutenant Colonel William"The F-20, Saga of an FX" ''Air University Review'', May–June 1986. The truth behind this jump in numbers is Northrop pressed the designation "YF-20" as they wanted an even number, in order to s ...

Faucett F-19
__NOTOC__ The Faucett F-19 was a 1940s Peruvian eight-seat high-wing transport monoplane built by the airline Faucett Perú for its own use. Development To meet its own requirement for an eight-seat transport the airline's engineering department designed and built the Faucett F-19. The design was based on the Stinson SM-1 Detroiter with improvements to meet the airline's specific operating requirements. The F-19 was a high-wing braced monoplane with a fixed tailwheel landing gear or floats. The cabin sat two crew and six passengers. Some aircraft were used for cargo work with no main cabin windows. 36 examples were built between 1934 and 1946. The aircraft was powered by an 875 hp (652 kW) Pratt & Whitney Wasp radial engine but the seaplane version use a 600 hp (447 kW) Pratt & Whitney Wasp radial engine. Most of the aircraft were built and used by the airline but a number were supplied to the Peruvian Government. Specifications (Landplane) Referenc ...

Focke-Wulf F 19
The Focke-Wulf F 19 ''Ente'' (German: "Duck") was a German experimental "canard" aircraft in the late 1920s. Design The F 19 Ente was a high-wing monoplane with a canard layout and fixed tricycle undercarriage. The pilot sat in an open cockpit, while an enclosed cabin was provided for two or three passengers. The canard was mounted on short struts above the nose of the aircraft, ahead of the cockpit, and the two engines were housed in nacelles mounted under the wings. The F 19 design was set so that the front stabilizer would stall some moments before the rear-mounted main wing, which in theory made the ''Ente'' virtually stall-proof. Operational history The first example flew on 2 September 1927 but was destroyed on 29 September during a demonstration of single-engine flight, after a control rod snapped. Focke-Wulf co-founder Georg Wulf was killed in the crash. Nevertheless, a second aircraft (''D-1960'') was built, flying in late 1930. This was used for a promotional tour o ...
