Would someone please explain why it is a relief if/that it's not the batteries? If it is a second flaw, why would that be better? And I know I'm in the dense minority who just don't get it because the huge swing (down then back up) in Boeing share value was attributed specifically to this by expert analysts.
Cards on the table, I'm tentatively thinking that the burn reflects a point of origin within the ceiling, that the Ethiopian official's initial comment sounds authentic, and that a "galley fire" capable of burning through the skin would have communicated further into the cabin as well.
