A safety-escort tug that ran aground two years ago on Prince William Sound's Bligh Reef went off course because of a captain who was playing video games, according to a report from the U.S. Coast Guard. The tugboat ran aground at the very same site where the Exxon Valdez disaster occurred. The tugboat Pathfinder was part of a navigation safety system established in the aftermath of the 1989 oil spill and was designed to guide oil tankers through the sound after they fill up with crude at the trans-Alaska pipeline's maritime terminal in Valdez.
But the tug boat operated by the Crowley Marine Services ended up striking the same submerged reef that ripped open the hull of the Exxon Valdez supertanker, causing the worst tanker spill in U.S. waters.
