NTSB: Boeing 787 battery shows short-circuiting
WASHINGTON (AP) â¿¿ The Boeing 787 Dreamliner battery that caught fire earlier this month in Boston shows evidence of short-circuiting and a chemical reaction known as "thermal runaway," in which an increase in temperature causes progressively hotter temperatures, federal accident investigators said Thursday.
It's not clear to investigators which came first, the short-circuiting or the thermal runaway, National Transportation Safety Board Chairman Deborah Hersman said. Nor is it clear yet what caused either of them, she said during a news briefing on the board's investigation.The fire took place aboard a Japan Airlines 787 shortly after it landed at Boston's Logan International Airport on Jan. 7. All the passengers had left the aircraft, but a cleaning crew noticed smoke in the cabin 26 minutes after the plane arrived at its gate. It took firefighters nearly 40 minutes to put out a battery fire in the rear auxiliary power unit. ___ Netflix stocks soars 41 percent after strong 4Q report SAN FRANCISCO (AP) â¿¿ Netflix's rollercoaster ride on Wall Street surged to new heights Thursday.
