Fighter, air refueling and special operations aircrew participate in a water survival training course led by a U.S. Air Force survival training expert (grey) at the Lowestoft College pool in Lowestoft, England, May 22, 2014. The class is mandatory for aircrew operating over a body of water. Harsh sea conditions off the coast of England present a major danger and can force pilots to adjust training flights to take place over land. Ultimately, this shift may lead to increased aircraft noise heard by U.K. communities. (U.S. Air Force photo by Staff Sgt. Thomas Trower/Released)
