"Engineering experts probing the Gulf of Mexico oil spill exposed holes in BP's internal investigation as the company was questioned Sunday for the first time in public about its findings.
BP's lead investigator acknowledged that the company's probe had limitations.
Mark Bly, head of safety and operations for BP PLC, told a National Academy of Engineering committee that a lack of physical evidence and interviews with employees from other companies limited BP's study. The internal team only looked at the immediate cause of the April disaster, which killed 11 workers and unleashed 206 million gallons of oil into the Gulf."
