Five weeks after the BP oil rig exploded and sank in the Gulf, the leak has been plugged:
Engineers have at least temporarily stopped the flow of oil and gas into the Gulf of Mexico from a gushing BP well, the federal government's top oil-spill commander, U.S. Coast Guard Adm. Thad Allen, said Thursday morning.
The "top kill" effort, launched Wednesday afternoon by industry and government engineers, had pumped enough drilling fluid to block oil and gas spewing from the well, Allen said. The pressure from the well was very low, he said, but persisting. The top kill effort is not complete, officials caution.
Update: From the New York Times:
NEW ORLEANS — In another serious setback in the effort to stem the flow of oil gushing from a well a mile beneath the Gulf of Mexico, BP engineers said Saturday that the “top kill” technique had failed and, after consultation with government officials, they had decided to move on to another strategy.
