From what I understand, locking up the Dreamliner batteries in a fireproof container is one of the steps they took to limit the severity of any potential future issues. The idea being that the batteries don't have to be perfectly safe if they can't take down the airplane.
Yeah, I'm leaning heavily towards this not actually being the batteries this time. In a way, that is kind of worse I think since it means they are not dealing with a known problem.
heavily electrified big vessel? like submarine or a ship. At least at the start, there were a lot of fires from wires and other pieces of electric equipment. And you can't just go with extra thick wires in the plane design.
From that video, if it was the batteries, someone moved them, and then set them on fire.
The batteries are nowhere near there. They're low on the plane, one set near the wings and one forward. That's maybe the APU, though more forward than I'd expect. Looks more like the cabin, maybe even the "flight attendant rest area" which is above the cabin.
My guess: random electrical. Or someone smoking carelessly.
