Ambitious Effort Begins to Contain All Spill Oil.

NEW ORLEANS -- Crews removed a cap from atop BP's out-of-control well in the Gulf of Mexico on Saturday, beginning an ambitious engineering effort that could fully contain the huge oil leak but will also make matters worse, at least temporarily. Live video showed the cap, which had been diverting 15,000 barrels of oil a day to a ship on the surface, being lifted off the well at the seabed. As the cap was moved away, oil gushed anew from the well. [ABSTRACT FROM PUBLISHER]
