Here is what I tell my students: In the future (after the limits of oil runs its course), airplanes will still need a burnable fuel. The only answer that I can think of is hydrogen (generated by nuclear)...

Despite all these dire predictions isn't the US now a net exporter of fossil fuels?JohnB wrote:The issue isn't the availability of airframes or even pilot training or the "disparity of wealth" talk (aviation had always been relatively expensive, but people managed a way to do it) it's fuel.
Listening to some of the politicians (and the wealthy activists who have their ear), gasoline will be a thing of the past in 30 years.
IF it's avalable, it will be so expensive to make warbird flying out of reach for many who now do it. If you can afford a Mustang, $30 a gallon gas may not be an issue, but what about the lower end warbirds? Not many guys will be flying L-birds or trainers. Bombers and transports...forget about it.

There is still a tremendous amount of oil and gas underground. In the next 25 years, many (most?) automobiles will switch to electric power (batteries), leaving petrochemicals for ships, aircraft, and other vehicles which need higher energy density. Society isn't giving up ships and aircraft powered by oil and its derivatives any time soon.

China is already starting that transition, and has announced that they will be entirely out of coal use during this decade (they are in the process of wholesale construction of nuclear plans).

Found this photo. October 28, 2020 the Collings Foundation Hellcat on the road to the facility in Hudson, MA. Wonder if it will ever fly again?

It is hard to take such predictions with any measure of seriousness.

Especially as we see battery operated vehicles shift the energy source away from gasoline.

Yes, but only shifts the energy source to natural gas.
