Boeing's 787 certification flight has landed.
The flight was Boeing's final certification test for the battery system it redesigned following smoke and fire incidents in January. Boeing Co. said the test would show the Federal Aviation Administration that the new system performs as intended "during normal and non-normal flight conditions."
A 787 destined for LOT Polish Airlines left Paine Field in Everett at 10:39 a.m. and landed at 12:30 p.m.
