WASHINGTON (AP) — An investigation of a battery fire aboard a Boeing 787 shows that mechanics and firefighters made repeated, unsuccessful attempts to put out the blaze through smoke so thick they couldn’t see the battery.

The documents released Thursday by the National Transportation Safety Board paint a more dangerous picture of the Jan. 7 fire than previously portrayed.

The Japan Airlines plane had just landed after an overseas flight. It was parked at Boston’s Logan International Airport when a cleaning crew smelled smoke. The 184 passengers had departed the plane six minutes earlier, and the 11-member flight crew had departed one minute earlier.

Firefighters used thermal-imaging cameras to locate the hissing battery with flammable liquid flowing down its sides in the intense smoke. It appeared as a white glow radiating heat waves.
