re: Containment Dome status???

A BP-chartered vessel lowered a 100-ton concrete-and-steel vault onto a ruptured well in the Gulf of Mexico on Friday, an important step in a delicate and unprecedented attempt to stop most of the gushing crude fouling the sea.

Underwater robots guided the 40-foot-tall box into place. Now that the contraption is on the seafloor, workers will need at least 12 hours to let it settle and make sure it's stable before the robots can hook up a pipe and hose that will funnel the oil up to a tanker.

"It appears to be going exactly as we hoped," BP spokesman Bill Salvin told The Associated Press on Friday afternoon, shortly after the four-story device hit the seafloor. "Still lots of challenges ahead, but this is very good progress."
