Pilots learned how to escape the entanglements of a parachute, how to communicate using a signal mirror (pictured) that can reflect sunlight up to 50 miles and how to survive in a one-man life raft until they get rescued during water survival training in Key West, Fl., Sept. 14 - 18, 2015. The signal mirror's viewing eye-hole lights up with an orange tint in order to help you focus on where you are shining the mirror. (U.S. Air Force photo/Lt. Col. Jeremy Boyd)
