Japan's airlines back Boeing

Safety officials have turned their attention away from the rechargeable lithium-ion battery on Boeing's (BA) new wide-body 787 Dreamliners as the likely culprit for several onboard fires. All 50 787s in service were grounded Jan. 17. Meanwhile, All Nippon Airways and Japan Airlines say they have had no second thoughts on orders for several dozen more of the planes. Boeing shares fell 0.4% to 75.03.
