NTSB to investigate Boeing 787 Dreamliner fire at London’s Heathrow Airport

Two Boeing 787 Dreamliner planes ran into trouble in England on Friday, with a fire on one temporarily shutting down Heathrow Airport and an unspecified technical issue forcing another to turn back to Manchester Airport. The incidents are unwelcome news for Chicago-based Boeing Co., whose Dreamliners were cleared to fly again in April after a four-month grounding due to concerns about overheating batteries. The fire at Heathrow involved an empty Ethiopian Airlines plane, which was parked at a remote stand of the airport after arriving at the airport. British police said the fire is being treated as unexplained, and that there were no passengers on board at the time of the fire. (AP Photo/Sang Tan)
