U.S. Air Force Airmen from the 823d Base Defense Squadron drift during a static-line jump, Sept. 16, 2016, at the Lee Fulp drop zone in Tifton, Ga. In the event that two Airmen collide, they’re trained to put their bodies in a “starfish” shape to prevent tangling in each other’s parachute. (U.S. Air Force photo by Daniel Snider)
