Photo Gallery: BP Oil Spill, Worst in US History

May 30, 2010 Updated: May 30, 2010

BP, attempting the "top kill" procedure to stop the Gulf oil spill, spent the last several days forcing heavy drilling mud into the compromised oil well, but failed to slow or stop the flow. The “top kill” plan was the most comprehensive and ambitious to date. The BP oil spill has now exceeded the 1989 Exxon Valdez spill, dispersing an estimated 18 million to 30 million gallons of crude oil into the Gulf of Mexico. With the US government, BP says they will move on to their next attempt, the Lower Marine Riser Package Cap Containment System, after several prior attempts to stop the leak failed.
