Very few people engage in private flying, and as I’ve pointed out factors like debt and lack of outcome on investment give young people good reason to not take up private aviation, so those numbers won’t be increasing. There won’t be any real support amongst politicians and the wider public to keep it going.
However there are alternatives. If you think a petrol powered light aircraft’s days are numbered, then why not look at investing in this to develop this technology as a potential future solution for recreational aviation:
So I'm confused. Do young people not fly because its expensive and the people associated with it are old and boring, or do they not fly because the mode of propulsion is associated with climate change? You actually negate one part of your argument with the other.
