"Engineers hoping to contain oil gushing from the mangled pipe beneath the Gulf of Mexico appeared to make important headway Sunday, as robot submarines jammed a suction tube into the pipe in an attempt to coax the oil to a ship on the surface.
"Officials for the oil company BP said they could not estimate how much oil and gas was flowing through the tube, nor what percentage of the leak was being contained, until Monday or Tuesday at earliest. They originally said the plan might suck up as much as 75% of the leaking oil."
