The link below goes to a paper that was sent to me by Lang Kidby and shows the difficulty at the present time in building an electric powered aeroplane that could fly from the UK to Australia.
Of course we have 3 years between now and then but from what I can make out, we’d need some pretty staggering improvements in the reduction of battery weight to be able to have such an Air Race. What do others think?
