Answer

A high G-force typically refers to accelerations above 5g for sustained periods or above 9g briefly. Fighter pilots regularly experience 7-9g during combat maneuvers, astronauts experience 3-4g during rocket launches, and roller coaster riders might experience 3-5g. Anything above 5g becomes increasingly dangerous without proper training and euipment, as it affects blood flow and can cause loss of consciousness.
