On April 20, 2010, the gigantic drilling rig Deepwater Horizon blew up in the Gulf of Mexico, killing eleven crew members and causing a massive eruption of oil from BP's Macondo well. For months, oil gushed into the Gulf, spreading death and destruction. Americans watched real-time video of the huge column of oil and gas spewing from the obviously failed "blowout preventer." The evening news showed heart-rending images of pelicans, dolphins, and other Gulf wildlife covered in oil.
