Pilots and astronauts both train to endure increased G-forces, and can be exposed to up to 9 G's during testing. G-LOC causes someone to lose consciousness for an average of 12 seconds, and remain disoriented when they wake. They may also have brief convulsions, vivid dreams, or complete amnesia afterwards. G-LOC can be fatal for a pilot flying at low altitude.
