I’m actually in favour of replacing most jet airliners with rail and maybe electric airships. Most short-haul flights can be replaced by rail; it’s much more pleasant than flying anyway. Jets can be reserved for long-distance journeys. Being able to hop on a blimp would be cool, even if it’s slower. We can make them much better and safer with today’s tech.

I don’t like the ‘green offset’ thing because it makes it look like we’re ‘doing something’ when it’s actually not doing much at all. If you want to be a utilitarian, it would be much more effective to just donate to an effective charity every time you fly.
