S65-19505 (28 May 1965) --- Astronaut Edward H. White II, pilot for the Gemini-Titan 4 prime crew,
is pictured during an extravehicular exercise in the Building 4 laboratory at the
Manned Spacecraft Center in Houston, Texas. White is controlling about the yaw (vertical) axis
while translating. He stands on a Balance Extravehicular Training Aircraft which is separated
from the level steel floor by a .001th-inch cushion of air. In his right hand White holds a zero-gravity
integral propulsion unit which is a self-maneuvering device used by an astronaut
in a zero-gravity environment. This condition is simulated in this training exercise.
White's spacesuit is pressurized to create a realistic training condition.
The simulated umbilical line is floated on air with the aid of eleven small air pads.
