Full Answer

The Deepwater Horizon oil rig exploded while drilling after an unanticipated bubble of methane gas rose to the surface from the new well. Of 126 crew members, 11 went missing and are presumed to have died in the explosion. About 4.9 million barrels of oil escaped from the well before it was finally capped.
