G-LOC incidents have caused fatal accidents in high performance aircraft capable of sustaining high g for extended periods. The condition is most likely to affect pilots of high performance fighter and aerobatic aircraft or astronauts but is possible on some extreme amusement park rides. G-force induced loss of consciousness (abbreviated as G-LOC, pronounced 'JEE-lock') is a term generally used in aerospace physiology to describe a loss of consciousness occurring from excessive and sustained g-forces draining blood away from the brain causing cerebral hypoxia.
