If, IF, this works, better late than never, though the conspiracy/doom guys will still say, too little, too late. And they could be right. All we need is a 100 mph hurricane to push that oil slick up onto shore and inland.
Hurricane season begins in 28 days, though few hurricanes ever appear until many days after that.

".....Bill Salvin, a (BP) company spokesman, said that crews had finished building a containment dome, a 4-story, 70-ton structure that the company plans to lower into place over one of the three leaks to catch the escaping oil and allow it to be pumped to the surface. The other two domes would be completed on Tuesday, Mr. Salvin said, and crews hoped to install all three domes by the weekend.
“That will essentially eliminate most of the issues you have with oil in the water,” he said.
The company was also trying on Monday to install a shutoff valve at the site of one of the three leaks. But according to David Nicholas, a BP spokesman, after the stormy weather of the weekend, the seas at the site had still not calmed enough by midafternoon for the valve mechanism to be hoisted safely out of a support ship."
