A Boeing-owned 787 production plane built for LOT Polish Airlines lands after a demonstration flight meant to be the final certification test for the 787's new battery system at Paine Field in Everett, Wash., Friday, April 5, 2013. Boeing called the flight "the final certification test for the new battery system." The next step will be for the Federal Aviation Administration to decide whether Boeing's battery fix is good enough for airlines to safely fly it again. The test was "to demonstrate that the new system performs as intended during normal and non-normal flight conditions," Boeing spokesman Marc Birtel said. The 787 Dreamliner has been grounded since mid-January because of smoldering batteries, including a fire on the ground in Boston. Boeing has designed what it says is a fix, including more heat insulation and a battery box designed so that any meltdown of the lithium-ion battery will vent the hot gases outside of the plane.
