The Northrop XP-79
The Northrop XP-79 is a unique aircraft. Designed by John K Northrop in 1942, the aircraft had a pilot operating the plane lying down and used two Westinghouse 19B turbojets. Originally, Northrop had a rocket motor in mind but scrapped it due to poor outcomes. The aircraft also had a monocoque skin rather than aluminum. In 1945, after a tragic event involving a test of the modified XP-79B, the company decided to cancel the project. The event also destroyed the aircraft.
