Japan's two biggest airlines ground all their fly-by-wire Dreamliners after 137 passengers escape smoking 787 via emergency slides

Japanese public broadcaster NHK reported that 137 passengers and crew on a Boeing 787 "Dreamliner" had to exit the plane via emergency slides after possible battery trouble and smoke forced the All Nippon Airways flight down at Takamatsu airport in southern Japan on a flight from Tokyo which was supposed to terminate at Ube in western Japan.

     Eight airlines now fly the 787: All Nippon Airways and Japan Airlines in Japan currently own 24 of the 50 delivered by Boeing since November 2011. The other operators are Air India, Ethiopian Airlines, Chile’s LAN Airlines, Poland’s LOT, Qatar Airways and United Airlines.
     Electrical systems, not mechanical ones, operate hydraulic pumps, de-ice the wings, pressurize the cabin and handle other tasks. The plane also has electric brakes instead of hydraulic ones.
