Largest US oil spill couldn't be plugged for 3 months
On April 20, 2010, an explosion aboard the BP-owned Deepwater Horizon oil drilling rig in the Gulf of Mexico killed 11 workers and triggered the largest offshore oil spill in American history. The leak could be plugged after three months, spilling an estimated 4.9 million barrels of crude oil into the Gulf, whose environmental damages are not yet fully understood.
