Another propulsion technique, creating high launch velocities, involves the use of elastic bands for "catapults". Walkalong gliding involves the continuous propulsion of paper airplane designs (such as the tumblewing, follow foil [15] and paper airplane surfer [16]) by soaring flight on the edge of a sheet of cardboard.
Time published an April 2, 1973 article, The Paper-Plane Caper, [2] about the paper airplane and its Kline–Fogleman airfoil. Also in 1973, CBS 60 Minutes did a 15-minute segment on the KF airfoil. CBS reran the show in 1976. [citation needed] In 1985, Kline wrote a book entitled The Ultimate Paper Airplane. [3]
He created paper airplanes since childhood and on Christmas Eve, 1966 learned that he could enter his designs in the First Great International Paper Airplane Contest. Pan American Airways offered to fly designs of paper airplanes that originated in Japan to the contest. He entered and, out of 12,000 entries from 28 countries, won in two ...
Advanced Supersonic Transport (AST) model in wind tunnel. The aircraft design process is a loosely defined method used to balance many competing and demanding requirements to produce an aircraft that is strong, lightweight, economical and can carry an adequate payload while being sufficiently reliable to safely fly for the design life of the aircraft.

The technique, used and patented by the Wright brothers, consisted of a system of pulleys and cables to twist the trailing edges of the wings in opposite directions. In many respects, this approach is similar to that used to trim the performance of a paper airplane by curling the paper at the back of its wings. [1]
Should one of the airplanes thus have made its way home, its journey would have helped to demonstrate the feasibility of slow-speed, low-friction atmospheric reentry. Critics have suggested that even a successful demonstration would lack probative impact beyond the realm of diminutive sheets of folded paper—they can only fall. [ 6 ]
