I have just looked at the Jackx 123 (posting 36) which I find very disturbing. I suggest all to give it a look. Cutting edge technology always has risks but not to learn, follow up & fix problems is unforgivable.
The 787 is cutting edge in so many ways. But I now feel that there have been so many other safety issues (not just the batteries) that the general airworthyness needs to be looked at carefully.
