Here is a brief summary:
BP says a mile-long tube, which they refer to as a "riser insertion tube tool" is sucking oil from the gushing well up and away. Their success in containing "some of the oil and gas" leaking from a pipe at the bottom of the Gulf of Mexico is the first progress they have made in over three weeks. Although this tube is not collecting all of the leaking oil, it is an important step in reducing the amount of oil being released into the water. It is estimated that 4.8 million gallons of oil have spilled into the Gulf since April 22nd. Furthermore, scientists have found vast plumes of oil in deep water, one of them 10 miles long.
