Boeing completes 'uneventful' test flight of 787 Dreamliner

CHICAGO (REUTERS) - Boeing Co completed what it called an uneventful flight on Saturday of a test 787 Dreamliner, its first since the airplanes were grounded more than three weeks ago after a series of battery-related problems.

The test flight to gather detailed information on the airplane's lithium-ion batteries lasted two hours and 19 minutes, taking off from and returning to Boeing Field in Seattle, Boeing said.

"The crew reports that the flight was uneventful," Boeing said in a statement.

The 50 Dreamliners in commercial service were grounded worldwide on Jan 16 after a series of battery-related incidents including a fire on board a parked 787 at Boston's Logan International Airport and an in-flight problem on another airplane in Japan.
