Thank you, FAA...
...but there's no way this little black duck will be getting on a B787 for at least a year or so.
I do not trust Boeing's 'fire box' solution to their as-yet-unexplained battery fires as it does nothing to explain how the last two 'non-fires' happened. All it does is (hopefully) contain any future fire. A couple of highly publicised flights in which the batteries didn't catch fire does not solve the problem.
This will only be ironed out when Boeing / Yuasa / ??? publish why the batteries reacted in the way they did. Anything else is a band aid solution (Bob Geldof not included).
Anon due to aviation involvement.
