Seems like the batteries are the culprit, but as of now no one knows why. They've x-rayed the batteries, put them through CT scans, disassembled them and checked the associated wiring bundles and battery management circuit boards. As of now, regulators have said that overcharging doesn't seem to be the issue, but we don't know much more than that. We'll have more coverage on this coming up.

Japen's agency essentially has said the same as the U.S. NTSB, to date, Cabe. No overvoltage. No overcharging, according to the reports I've seen.

Looking forward to reading your follow-up coverage on this, Chuck.

You have to wonder who in their right mind would get on the 787 after all this?

max take off weight of 787-9 is 251 metric tons (modification for long distanses 15700km), total force from engines 64.4tons

amazingly 787-3 (not in production) has near 170 tons weight and flight distance 5500km, total engine force 48 tons - look like very different plain, but with same design & engines.
