SERE specialists free-fall

FAIRCHILD AIR FORCE BASE, Wash. -- Survival, evasion, resistance and escape specialists performed static line and free-fall jumps from a CH-47 Chinook helicopter Nov. 6, 2012. 

A static line is a cord attached at one end to an aircraft and the other to the parachutist. As they fall from the aircraft, it causes the line to deploy their parachute. These jumps are normally conducted at 1,250 feet above the ground and can be as low as 400 feet.
