Boeing 787 Dreamliner Returns to Service

United and Boeing employees perform a ground check on a Boeing 787 Dreamliner after a flight from Houston at O'Hare International Airport in Chicago on May 20, 2013. The Houston-to-Chicago flight landed without incident and marked the return to service of United-owned Dreamliners after the airliner was grounded for 100 days by aviation regulators worldwide due to the overheating of onboard batteries.
