Inside History on Instagram: "Pilots undergo 9G force testing to prepare for the extreme physical stress of flying high-speed jets! During sharp maneuvers, up to nine times the force of gravity can pull blood away from the brain, risking vision loss or G-LOC (loss of consciousness). To prevent this, pilots learn Anti-G Straining Maneuvers (AGSM) to maintain blood flow and stay alert. The 9G test, often done in a centrifuge, ensures they can handle these forces safely during real flight. #history
