New Orleans, La. – In its first public grilling about what caused the April 20th explosion, BP's engineering team says eight failures led to the blast that killed 11 workers. BP says other companies are also at fault, including rig owner Transocean of Houston and Halliburton, which was in charge of cement work. The National Academy of Engineering committee says BP's report is limited to decisions made on the rig, not with management on shore. The report was also made without interviews of employees from other companies, or with an examination of key evidence. The drilling rig is still on the seafloor. The Interior Department asked the engineering academy to review the accident and come up with safety recommendations.
