The Bell XP-77 development was initiated by the United States Army Air Forces during World War II to produce a simplified "lightweight" fighter aircraft using non-strategic materials. Despite being innovative, the diminutive prototype proved tricky to handle and the project was canceled when the XP-77 did not deliver its projected performance.
The Bernard SIMB AB 10 was a French single-engine, single-seat, highly streamlined, cantilever, all-metal low-wing monoplane of advanced design. It first flew in 1924 but was not ordered into production.
