Boeing completes second 787 'Dreamliner' test flight

Test flights of the 787 were approved last week by the Federal Aviation Administration (FAA) after the plane was grounded for a month following a battery fire on an airplane that was being operated by Japan Airlines at Boston's Logan International Airport.

The agency has ordered U.S. airlines to stop flying the 787 since the mid-January battery fire and a similar in-flight incident on a plane in Japan.

Other worldwide aviation agencies quickly followed the FAA's lead, resulting in a worldwide grounding of the Dreamliner.

The FAA has not identified a time frame for the return of the 787 to regular commercial flight service.
