787s were grounded and they are now flying again, but it is a probationary period and people will be interested in every little thing that occurs to see if any patterns might be emerging. People are still nervous in Japan. The press in Japan will pick up on anything, feeling it is in the public interest, whereas these incidents may not get reported in English.
Part of me wonders whether there is a reluctance in the English press to follow any further, whether they just want to give these new planes a break, or if there is some other force at play.
Anyway, in the interests of freedom of information I have given a rough translation of the two articles above. Personally I feel it is better to know what is happening up at the sharp end where the majority of Dreamliners are putting in the exploratory miles.
At the same time I agree that this thread concerns the electrics, specifically Lion battery performance, so if this is off-topic then point taken.
