Pilots from the 355th Fighter Squadron prepare to go through water survival training, Oct. 28, 2018, at Naval Air Station Key West, Florida. The pilots, who are required to go through the course every three years, learn how to escape parachute entanglements and survive in a one-man raft in case of emergency, which helps them stay combat and deployment-ready.
