Bear,
Didn't ANA report a drop to zero voltage concurrent with the smoke event?
Yes, battery voltage went to ZERO because mother nature opened the circuit of the BAD DESIGNED BATTERY as i showed in the equivalent circuit of the probable sequence in an earlier post.
Mother Nature? I don't think so. Give BOEING some credit. Temperature is obviously addressed in the design, to what extent is not known, but HazelNuts39 has shown some interesting leads in the failed case.
Just because they got caught out in their assumptions about
propagation, does not infer that they let a high temp fail safe system out of the design.
I'm still looking at the "WhiteWad"....mesmerized.
