Million gallons of oil a day gush into Gulf of Mexico
Interviews with surviving Deepwater Horizon rig workers show how explosions led to what may be the world’s worst oil spill

An extraordinary account of how the Deepwater Horizon disaster occurred emerged yesterday in leaked interviews with surviving workers from the rig. They said that a methane gas bubble had formed, rocketed to the surface and caused a series of fires and explosions which destroyed the rig and began the gushing of millions of gallons of oil into the Gulf of Mexico, threatening wildlife and coastal livelihoods. Oil-covered birds caught by the outer edges of the 135-mile slick are now being found.
Word also came yesterday that the oil spill may be five times worse than previously thought. Ian MacDonald, a biological oceanographer at Florida State University, said he believed, after studying Nasa data, that about one million gallons a day were leeching into the sea, and that the volume discharged may have already exceeded the 11 million gallons of the 1989 Exxon Valdez disaster, widely regarded as the world’s worst marine pollution incident. Mr MacDonald said there was, as of Friday, possibly as much as 6,178 square miles of oil-covered water in the Gulf.
