I saw at least one “mad face” emoji reaction to your post.It'll never happen. Fossil fuels are here to stay forever.
Your comment is fact, not opinion.
”Fossil fuels” ARE here to stay, at least for the foreseeable future, especially with regard to aviation, as there is not another readily available fuel (short of building nuclear-powered aircraft, which was a plan that almost came to fruition in the late 50s & early 60s) that is suitably energy-dense to provide the power and range needed for our airplanes.
So, for those who are mad about fossil fuel, let’s hear your ideas?
