Dreamliners may take off soon

Boeing (BA) on Mon. began installing reinforced lithium-ion batteries on 5 grounded 787 Dreamliners in Japan, launching a process that's expected to get the technologically advanced wide-body jetliner in the air as soon as next week. The FAA and officials around the globe grounded all 50 787s in operation in mid-Jan. after defective batteries caused problems, including a smoking battery on a plane parked in Boston. Last week, U.S. regulators approved a revamped battery system. Shares fell 1.2% to 86.94.
