A crowd of onlookers gathers atop a Sunset District sand dune to watch the launch of McGill Glider No. 813N, by the Pacific Glider School at 33rd Avenue and Kirkham Street, on May 24, 1930. The gliders were launched via massive rubber bands. Pilots (many of whom were World War I veterans) controlled them with foot pedals and a single stick between their legs.
