Airman 1st Class Derrick Brown lectures an F-16 Fighting Falcon pilot on anti-gravity straining maneuvers as he spins in the centrifuge during the last training course Oct. 27, 2010, at Holloman Air Force Base, N.M. For 22 years, members from the Physiological Training Center have conducted flight acceleration training using a centrifuge which exposes aircrews to a high level of G-forces — a measurement of an object’s acceleration. This class was the last to go through the centrifuge training at Holloman. Airman Brown is an Aerospace Physiological Training Center technician. (U.S. Air Force photo/Senior Airman Veronica Stamps)
