In this image released by the National Transportation Safety Board and released Jan. 11, 2013, NTSB Investigator Mike Bauer works inside the Boeing 787 "Dreamliner" airplane under investigation at Boston's Logan Airport on Tuesday, Jan. 8, 2013, in Boston. The government stepped in Friday to assure the public that Boeing's "Dreamliner" is safe to fly, even as it launched a comprehensive review to find out what caused a fire, a fuel leak and other worrisome incidents this week. A fire ignited Monday, Jan. 7, in the battery pack of an auxiliary power unit of a Japan Airlines 787 empty of passengers as the plane sat on the tarmac at Boston's Logan International Airport. It took firefighters 40 minutes to put out the blaze. (AP Photo/NTSB)
