Paraglider: Test landing of the Tow Test Vehicle at Edwards Air Force Base in California. In the mid-1960s, NASA looked to develop an alternative spacecraft landing method to splashdowns. The project proposed the addition of a paraglider, known as the Rogallo wing, which astronauts would deploy during reentry and use to pilot a runway landing. While NASA planned to introduce the system to Gemini missions, NASA removed it from the program following a series of setbacks. Testing continued for data-gathering purposes, with 12 successful landings of the Tow Test Vehicle in 1965. By then, however, it was too late to include paraglider landings in Gemini or Apollo missions. Hoping to make use of its $165 million investment, NASA looked to incorporate the paraglider technology into future projects, such as the Apollo Applications Program, but the system was scrapped again as post-Apollo programs were cut by the end of the 1960s.
