ATLANTIC OCEAN- Cadets and crew aboard Coast Guard Cutter Eagle hold the national ensign and wait for orders to hoist the flag while transiting through the port of Charleston, S.C., Monday, June 29, 2009. The in port and underway ensigns are switched simultaneously so the ship always sails with an American flag flying. (U.S. Coast Guard photo/Petty Officer 2nd Class Etta Smith)
