Massport crews were venting smoke from a door at the bottom of the plane

The aft EE Bay Hatch?

The aft EE Bay Hatch?
No, just unclear language. I've seen pictures where both fwd and aft cargo hold doors are open, which one would expect them to be during a turnaround, and in one shot white smoke seems to be venting from the aft hold. Could be the hoover, as suggested above, might also be the aft EE compartment (again), or something else entirely. With Boeing's current luck in the art of electrickery in mind, however, my money's on an abnormal event in the EE compartment.

Those fastidious Japanese know how much the pax appreciate a well-groomed/hoovered plane - "According to Tweets from the Boston Fire Department, the fire was in “a compartment with batteries and other electrical components.”

If you look at the video, there appears to be smoke coming from under the fuselage fwd of the aft cargo door. That is the aft EE bay hatch location.

Hmmm. Worrying?

Maybe a bit too much smoke for a hot hoover . . .

Boeing 787 Dreamliner reported on fire at Logan International Airport - Boston.com

Massport Fire Rescue Chief Robert J. Donahue said firefighters encountered heavy smoke in the entire cabin of the plane and used thermal imaging devices to determine the source of the fire. “We found a fire condition about ‘midships in the avionics compartment underneath,” he said. He said the fire began in a battery that was part of an auxiliary power unit that is only used when the plane is on the ground and its engines are turned off.

Source of fire

It is indeed interesting that there are reports of fire having started in the battery compartment or the avionics bay. I found these quotes from Boston Herald interesting:

“We don’t want to speculate, but it could have happened after it arrived,” said Freni, adding that all luggage was off the plane at the time the fire was reported.

Massport Fire Chief Robert Donahue said firefighters saw “heavy smoke conditions” in the entire cabin when they arrived and determined the source of the smoke was the plane’s avionics section where the batteries are located.

Freni [Massport Aviation Director] said he believed that this particular plane had gone into service only recently, in the past few weeks.

He said he had seen the plane land from his office. “I saw it taxiing. There was no indication of smoke at that point,” he said.

Flight 8 was expected to turn around and fly back this afternoon, but it has now been grounded.

According to the Associated Press, the Port Authority fire chief said the fire began in a small battery pack for the plane's APU. The firemen used infrared equipment to find the source of the smoke and fire and had it out within 20 minutes. It did flare up again when one of the batteries exploded. The plane landed normally without problems with 173 passengers and a crew of 11. Everyone had left the plane, but there was a mechanic on board that noticed light smoke in the cockpit after being onboard for 15 minutes and reported it to authorities. The cause of the batteries overheating is not yet known.

A tip of the cap to the mechanic for getting it right, and getting the fire team out there. Perhaps he prevented something much worse from coming to pass.

Have you guys ever seen a thermal runaway? Just have a quick search on YouTube. I've seen batteries go before and it is not something I'd like to be near to again!

Agree, I've seen a number of videos of Lithium-ion batteries in consumer appliances going up and it's quite scary. I don't know anything about the type used in the 787 but I'd hate to be around if one of them that size went off like the consumer ones!

+1, and from personal experience any battery going up definatley isn't fun, especially in a confined space...

Rather them than me going into the unknown.... Just thinking of that China Airlines 737 that went up at Okinawa and how quickly that went up. Brave lads
