A cap is back in place on BP's broken oil well after a deep-sea blunder forced crews to temporarily remove what has been the most effective method so far of containing some of the massive Mexican Gulf oil spill. Engineers used remote-controlled submarines to reposition the cap after it was off for much of the day. It had captured 700,000 gallons (2.7 million liters) of oil in 24 hours before one of the robots bumped into it.
