jkinney3 was one of several readers to send in news of recently discovered internal documents from BP which indicate the company knew "there were serious problems and safety concerns with the Deepwater Horizon rig far earlier than those the company described to Congress last week." According to the New York Times, "The documents show that in March, after several weeks of problems on the rig, BP was struggling with a loss of 'well control.' And as far back as 11 months ago, it was concerned about the well casing and the blowout preventer." Reader bezenek points out this troubling quote about BP's inconsistent risk assessments: "In April of this year, BP engineers concluded that the casing was 'unlikely to be a successful cement job,' according to a document, referring to how the casing would be sealed to prevent gases from escaping up the well. The document also says that the plan for casing the well is 'unable to fulfill M.M.S. regulations,' referring to the Minerals Management Service. A second version of the same document says 'It is possible to obtain a successful cement job' and 'It is possible to fulfill M.M.S. regulations.'"
