Helicopters drop sandbags as oil spill grows

Black Hawk helicopters peppered Louisiana’s barrier islands with sacks of sand to bolster crucial wetlands against the four million gallon-and-growing Gulf of Mexico oil spill.

At the site of the ruptured well a mile underwater, a remote-controlled submarine shot chemicals into the massive leak to dilute the flow, further evidence that BP expects the gusher to keep erupting into the Gulf for weeks or more.
