This Jan. 17, 2013 photo provided by the Japan Transport Safety Board shows the distorted main lithium-ion battery, left, and an undamaged auxiliary battery of the All Nippon Airways' Boeing 787 which made an emergency landing on Jan. 16, 2013 at Takamatsu airport in Takamatsu, western Japan. An investigation into the battery that overheated on a Boeing 787 flight in Japan found evidence of the same type of "thermal runaway" seen in a similar incident in Boston, officials said Tuesday, Feb. 5, 2013.
