The Mitchell Wing B-10 Ultralight Motor Glider – U.S. Pacific George Worthington, holder of eight world records in hang gliding and author of the book In Search of World Records, wrote in the book..."I predict that the Mitchell Wing will be the highest performance foot-launched hang glider we'll see for a long time."[9]

This presented the Rogallos with two choices: defend the patent and receive royalties for each kite manufactured or let people fly these newly affordable wings for free. In a gesture unparalleled in aviation history, the Rogallos decided to give their invention to the people of the world and let manufacturers freely produce gliders using their patented invention.[18]

Several Langley employees shared Rogallo's enthusiasm for the innovative flight technology and even conducted manned flexible wing flight research during weekends on the Outer Banks with privately owned equipment. Although qualitative in nature, these investigations proved "valuable in providing quick answers and indicating promising directions for the much more costly and time consuming instrumented but unmanned NASA flight research."[7]
Francis Rogallo gave the U.S. government royalty-free license to use its patents, which it did in a ceremony in Washington on July 18, 1963. In a short speech, Rogallo expressed his hopes for the invention: "We feel confident that the civil and military agencies of the government will carry on this work, and we hope private industry will promote use of the concept for business and pleasure as effectively as they have for astronautics and military aeronautics."[17]
