The Ryan X-13 Vertijet makes its first vertical take off and landing, marking the first time a jet-powered aircraft successfully completed a VTOL flight. Militaries around the world at the time were experimenting with the concept of VTOL as a way of having aircraft that could take off and land from areas with no runway. While the X-13 was tested successfully, the program was cancelled after only two years. The X-13 concept proved unfeasible for the United States military due to a variety of issues, including payload and range capabilities.
