TRAINING - GEMINI-TITAN (GT)-5 - TX

S65-35563 (18 June 1965) --- Astronauts L. Gordon Cooper Jr. (left), command pilot; and Charles Conrad Jr., pilot, the prime crew of the Gemini-5 spaceflight, prepare their cameras while aboard a C-130 aircraft flying near Laredo, Texas. The two astronauts are taking part in a series of visual acuity experiments to aid them in learning to identify known terrestrial features under controlled conditions. Knowledge gained from these experiments will have later application for space pilots identifying terrestrial features from space. Dr. John Billingham, chief, Environmental Physiology Branch, Crew Systems Division, is in charge of the Visual Acuity Experiments.
