Curtiss-Wright X-100: The Experimental Aircraft That Proved Tilt-Propeller VTOL Was Possible

The Curtis Wright X-100 was an experimental aircraft developed in the late 1950s to test the viability of vertical take-off and landing (VTOL) using tilting propellers. While it successfully transitioned from vertical to conventional flight, it faced significant stability and safety challenges before being transferred to NASA and eventually the Smithsonian Institution.
