A U.K. government inquiry blamed BAE Systems and QinetiQ Group for safety failings that caused an explosion on a Royal Air Force Nimrod reconnaissance plane over Afghanistan in 2006, killing all 14 on board... “The cause of the accident will never finally be determined,” BAE said in an e-mailed statement...”QinetiQ wishes to take time to digest the report fully before making any detailed response,” the company said in an e-mailed statement. “We want to emphasize that QinetiQ will seek to learn from all that the report says.”
