Bell XF-109


The Bell XF-109 was a proposed Mach 2 vertical take-off and landing (VTOL) fighter that never proceeded past mock-up stage. It was to have eight jet engines: two mounted vertically in the fuselage, two mounted horizontally in the fuselage, and two in each of two wingtip pods that were to rotate so that they could be used in both horizontal and vertical flight.
