I just read the 18 March 2013 issue of Aviation Week. On pages 28-29,
there are two articles on the 787 battery investigation results and
proposed fixes.

What caught my eye, and apparently that of the investigators, was that
there was never an all-up test of the 787 battery charging system with
the actual Yuasa-made production battery. They were tested
independently, but there is no record of them ever being tested
together.

So, they're doing things like our CONgress critters do now, eh?

Anyway, the fixes are basically to isolate the cells better so if one
self-destructs, it cannot take the other cells with it, venting of
smoke overboard, better electrical insulation all around, and a lot of
black-box data recording so they can figure out root cause next time.

Did they ever ask Elon Musk what he had in mind? He offered to fix it
for them gratis.
