Re: "having a load of Lithium batteries in the hold sounds like a bad idea to me."
PanAm flight 103 was brought down by what looked like a Toshiba radio stowed in the hold. Maybe the best thing to do would be to ban ALL electrical or electronic equipment ANYWHERE on every aeroplane?

And perhaps you remember all the problems with the lithium batteries in the Boeing Dreamliner -- and these were part of the Boeing design! Perhaps we should ban ALL lithium batteries from aeroplanes and go back to good old NiCads...or even the trusty lead acid sort?

Then there's the wetware problem -- pilots who are mentally unbalanced and crash aeroplanes into mountains....what to do about that?

I really don't think the authorities are doing enough to "keep me safe". I think I'll stop flying in aeroplanes. Oh wait....crossing the road is more dangerous than flying.....
