Ryan X-13 Vertijet
The Ryan X-13 Vertijet (company designation Model 69) is an experimental tail-sitting vertical take-off and landing (VTOL) jet aircraft built by Ryan Aeronautical and flown in the United States in the 1950s. The main objective of the project was to demonstrate the ability of a pure jet to vertically take off, hover, transition to horizontal forward flight, and vertically land.
