A 100-ton containment box is close to being in place over a blown-out well that's been spewing oil into the Gulf of Mexico.
Douglas Peake, the first mate of the supply boat that brought the box to the site, confirmed a radio transmission from the nearby vessel lowering the device that said the device would be in position over the well soon.
The transmission said undersea robots were placing buoys around the main oil leak to act as markers to help line up the 40-foot box.
A crane late Thursday lowered the containment vessel designed to collect as much as 85 percent of the oil and funnel it up to a tanker. Such an operation has never been tried at that depth, about a mile down.
Oil giant BP PLC is in charge of cleaning up the mess. It was leasing a drilling rig that exploded 50 miles out in the Gulf of Mexico.
