Curtiss-Wright VZ-7, a Manned Quadcopter From the 1950s

In the 1950s the US Army command thought they needed a flying machine that would sort of fill the gap between an automobile and the helicopter. This gave way to several design projects collectively known as ‘flying jeeps.’ The first of them to rise in the air was Curtiss-Wright VZ-7 VTOL aircraft created by the company’s Santa Barbara Division (formerly the Aerophysics Development Corporation).
