NEW YORK -- Boeing ( BA) conducted a two-hour test flight on Monday of a 787 Dreamliner with a redesigned battery system. The aerospace giant said the flight "went according to plan." Boeing said it plans to analyze the information from the flight, and if it deems the test successful will take another flight in a few days to gather more data to submit to the Federal Aviation Administration. Boeing hopes to get the planes in the air in a few weeks. They have been grounded since January after the lithium-ion batteries on two planes overheated.
