-- Two Japanese airlines grounded their fleets of the Boeing 787 Dreamliner, which has been beset by a string of mechanical and other problems, after an All Nippon Airways flight made an emergency landing Wednesday.
Japan Airlines has seven of the airplanes and All Nippon Airways normally flies 17.It was not clear how long the JAL and ANA flights would be grounded.
ANA Flight 692, with 129 passengers, made an unscheduled landing at Takamatsu airport in Japan, said airline Vice President Osamu Watanabe, after a battery alarm signal activated on the plane.
Those on board reported a burning smell in the cabin. One alarm indicated smoke in a forward electrical compartment, officials said.
