BP admitted today its managers on the Deepwater Horizon missed key warning signs in the hours before the explosion aboard the oil rig, but an internal investigation put much of the blame on other companies involved in the well.
A 234-page report described eight main causes for the blast, which killed 11 men and created an environmental disaster. The full report also contained - within the detailed analysis of the operation - a comprehensive, minute-by-minute timeline of every event, as it happened. BP have also produced a graphic video animation.
