It was not used for its original purpose, but in the late 1960s it was converted into a sport in which a man hangs from it and glides down a slope, and it became known as the Rogallo glider and spread to Europe and Japan in the 1970s. … *Some of the terminology that mentions "Rogallo, FM" is listed below.
