My range-anxiety comment, with regard to WWI era aircraft, was made with my tongue firmly embedded in my cheek. My limited experience of aircraft of that era is at Old Warden and I wouldn’t be surprised to find that one eye was permanently focussed on the landing strip anyway, just in case.

It seems as far as classic cars are concerned, electric conversions are hugely expensive and massively reduce the value of the vehicle.

Possibly an over-generalisation and it may change in the future but that’s my current impression.

In respect of aeroplanes, who knows?
