In principle, you are right. Cheaper than coal renewables are winning. Don't forget though, that fighter jets can't operate on batteries.
Patriotic red blooded Americans use renewable energy
Gas turbines can run on a variety of fuels, natural, synthetic or a mixture of both. It’s actually one of the reasons that a turbine was chosen for the M1.
It is made with from water, carbon dioxide and energy. Use green energy and atmospheric CO2, and it is carbon neutral.
You totally can fly on biofuel, but it is not cheap compared to fossil fuel without externalized costs.
It's specifically bad faith to say it as if it does somehow matter in the grand conversation, when the actual fallout is extremely small. Pretty much nobody is saying we must remove 100 PER CENT OF ALL FOSSIL FUEL USAGE EVERYWHERE FOREVER, just that we need to move off it.
I'm convinced.
