Dreamliner Nightmare: Investigations Begin - lithium ion rechargeable battery
Air safety officials from the United States arrived in Japan to inspect a Boeing aircraft.

Earlier this week, 787 aircraft landed urgently after rechargeable Lithium
Overheating of ion batteries
The landing of the aircraft includes the deployment of escape routes for passengers and crew, the sixth landing of the model in less than a week.
The risk of fire caused by overheating of batteries has become a major problem for Boeing to cut costs.
Since the Japanese domestic flight incident, edge's new aircraft has prompted airlines to Close 787 of all 50 operations in the world.
Since the pilot was forced to land dramatically on Wednesday, the ANA Dreamliner has remained on the taxiway at Komatsu Airport in southwest Japan, as smoke alarms are clearly related to lithiumion battery.

A spokesman for Japan's Transport Safety Board, Boeing, arrived in Komatsu for a survey in Japan (JTSB)said.
"We removed the battery yesterday and are checking the aircraft and its components with US officials today," said spokesman takaashi Mamoru . ".
Batteries for advanced electronic equipment for Dreamliner are manufactured by GS Yuasa, Japan, in a complex global supply chain, one of the many contractors caused Boeing to delay three years before delivering its first 787 aircraft to ANA in 2011.
ANA said electrolyte leaks and burn marks were found on the metal housing of the battery. GS Yuasa -
While defending its reputation for quality
He warned the investigation could take weeks.
Hideyo Kosugi, JTSB investigator, said one theory being considered is that overload protection devices may be inadequate.
"I'm sure too much current or too-
"The voltage of the battery is very high," Mr Kosugi said . ".
A long shutdown could seriously exacerbate the crisis at Boeing, which suffered a series of failures in Japan and the United States a week before the ANA incident.
Hans Weber, an independent security and defense expert, said Boeing was too optimistic about the benefits of its global outsourcing strategy, which aims to build 787 aircraft.
About three of the aircraft's components are from Japan.
"Boeing acknowledges that it underestimated the level of management oversight and engineering support needed to provide suppliers with a highly decentralized supply chain," Mr Weber said . ".
"If Boeing did a better job in this, it would not, in my opinion, experience the technical problems it faces.

Said that if any defects on the aircraft are eliminated, it still expects to deliver three more planes before the end of the march.
Meanwhile, Australia's Qantas said it was cutting the request for a Dream Plane by one, but noted that it had planned to do so before the plane was grounded and that it still had 14
