At least two different planes as one JAL and the other ANA.
JAL 787 still on ground in BOS. As all we know is that tonight's landing was prompted by a 'battery malfunction warning', we won't know what battery it is.
I suspect that this was probably an over-reaction to something that must be at the back of the minds of all 787 flight crew. If it was a genuine battery malfunction then we have to start considering whether there is any significance in the fact that so many incidents have occurred in Japanese operated 787's.
Is there something in the 'customer electrical specification' of the of the planes built for JAL and ANA that could be initiating these fires/warnings?
Just a thought.
