OSU PG-I
The PG-I was an experimental glider built by a team of Ohio State University undergraduates, and was notable for being constructed entirely of paper and cardboard. == Background == Prompted by a 1970 paper airplane contest jointly sponsored by the Columbus Dispatch newspaper and the Columbus-based Center of Science and Industry, a team of six OSU students, led by David W. Hall, decided to build the world's first piloted paper airplane.
