Gemini-Titan (GT)-10 - Weightlessness Training - Wright-Patterson AFB, OH

S66-28782 (1 April 1966) --- Astronaut Michael Collins, prime crew pilot of the Gemini-10 spaceflight, experiences a condition of weightlessness during zero-gravity egress training. A KC-135 Air Force plane, flying a parabolic curve, creates a weightless environment as a training exercise in preparation for spaceflight. The Hand-Held Maneuvering Unit in his right hand produces controlled thrust for moving about. Photo credit: NASA
