An in-flight fire is a nasty thing.  It's not like you can roll down the windows to get fresh air and then pull over to put the fire out.

It also seems that more questions keep coming up about these incidents and the initial testing/certification. At this point, I would be very worried at Boeing as this seems to be an issue that will not go away with some simple changes!

Thank you Charles for keeping us at DN updated regularily!

I'm sure that  NTSB will implement a test with a "thermal runaway battery state" to check B787 for the worst scenario again.

There was a lot of information about the battery but nothing about the plane maintenance procedures. The Li-ion batteryes require complex electronics control which are in standby or switched off during " while the aircraft was being cleaned after a flight".

Well this is certainly a troubling development in your excellent continued coverage of this, Chuck. Considering the number of battery incidents that occurred so quickly in succession, I would say this was a gross underestimation on their part. I would expect more from a company like Boeing, especially when lives are at stake. It's not like they started making airplanes yesterday.
