Okay, so prepared this post yesterday and and tried to write a thoughtful and balanced blog about the whole subject of climate change and the future of propulsion in aviation and then the website crashes and I lose it all. And then I had to rush and now I finally get around to post yesterday’s strip. Sigh. Anyway, I just wanted to re-write the main closing point: I know it’s an emotionally charged topic for some people, but please don’t start a war in the comment section. Be polite and courteous! I would really be interested in hearing the opinion of people who know more about the issue of the future of aircraft engines than me. (Which is easy, because I know almost nothing about it.) Will there ever be a viable alternative to fossil fuels in airplanes?
