GULF OF MEXICO - Aerial view of oil being burned from the Deepwater Horizon/BP incident, May 19, 2010. Favorable weather conditions allowed burns to total more than nine hours. The burns are part of an effort to reduce the amount of oil in the water and are part of the joint federal, state and BP effort to aid in preventing the spread of oil following the April 20 explosion on the mobile offshore drilling unit, Deepwater Horizon.
