On May 9th, 1976, Grand Canyon National Park permitted a NPS approved Hang Gliding Feasibility Test that you can watch HERE. Amazing footage. There’s no sound, so try using the song below. (Thx BTBN)

Above are photos from the Arizona Hang Glider’s Association’s archive (not taken during the GCNP test). There are loads of old photos and newspaper clippings there, so go and take a peak.
