Just saw this on TV Japan's live feed... the anchorwoman
reports that one of EVA AIR's Airbus A330 suffered an
inflight accident and made an emergency landing at
Tokyo Narita Airport. Nearly 50 passengers and/or crew
members were injured. Only a handful were serious
injuries. The video shows passengers being taken
to hospitals in ambulances. Most were Japanese and
Taiwanese nationals... no report of American passengers
aboard. One uninjured Japanese passengers interviewed
said the pilots were flying the plane like a "roller coaster."

Will keep watching and update this... my Japanese is
average so I'll try to get more details in English...
