What is high G-Force flight?

High G-force flight refers to maneuvers in aircraft, particularly military jets, that expose the pilot to high levels of gravitational force. For instance, during such flights, pilots can experience up to 9 G's (nine times the force of gravity), which puts immense pressure on the body. A G-force of this magnitude can make it feel like every atom in the body is pulling apart, significantly affecting visibility and requiring physical tensing, mainly in the legs, to maintain consciousness by forcing blood back up to the head 1 2.
