Overcharging batteries eyed in Boeing 787 mishaps - Article Photos 3/3

All Nippon Airways' Boeing 787 "the Dreamliners" passenger jets park on the tarmac as Japan Airlines' Boeing 737 taxies by them at Haneda airport in Tokyo, Friday, Jan. 18, 2013. U.S. safety officials and Boeing inspectors joined a Japanese investigation Friday into the 787 jet at the center of a worldwide grounding of the technologically advanced aircraft. In the wake of the incident, nearly all 50 of the 787s in use around the world have been grounded. Aviation authorities in Japan have directed ANA, which owns 17 of the planes, and Japan Airlines, with seven, not to fly the jets until questions over their safety have been resolved.
