Members of the 418th Flight Test Squadron perform tests on an experimental parachute system called the Guardian Angel Advance Parachute System. These GAAPS system tests involve fixing the parachute system to a dummy, which will range in weight from 250 to more than 400 pounds, depending on the weight each test requires. The system is designed to take the place of the current one, which was originally created in the 1960s. (U.S. Air Force photo/Rob Densmore)
