August 19, 2012 (BOSTON) --
For just the second time in 131 years the USS Constitution sailed under its own power Sunday for a big anniversary.The world's oldest commissioned warship afloat sailed for about 10 minutes on the 200th anniversary of a major battle.
The short trip marked the day two centuries ago when the Constitution bested the British frigate HMS Guerriere in a fierce battle during the War of 1812.
