    I read somewhere that after 9/11 there was a small, but noticeable increase to air temps over the US when they shutdown air traffic and the particulate clouds stopped forming & reflecting sunlight.

    :what-the-hell:

      While that's a possibility, I'm really skeptical this is a proven fact. Weather is too chaotic of a system for a small variation in temperature to be specifically attributed to something like that, even averaged across a continent and a 2 week period.

    Nah planes aren't real. You actually think there are big metal birds that can fly without flapping their wings!?!?! Get a grip. The government just puts us in a metallic tube for 6 hours to cover up the existence of teleportation devices.

      Environmentally? Fuck nah. Massive expenditure of energy to fly vs just coast on tires or rails.

        It's kind of a shame that a cross-country train is way more expensive than a plane here, by about an order of magnitude. I assume it's because of the labour cost of 6 hours vs 30? or that it's catered to a few luxury passengers rather than packing passengers in like sardines? Probably, something like that

          Tracks and bridges are not cheap to maintain.

            I imagine that comes into the emissions cost per mile or something (likewise, runways, plane maintenance etc etc)

              The coming age of electric air travel is going to be noisy but cleaner.

              I have mixed feelings about the constant sound of drones in my life.

                I'd hope that commercial (or public) air travel won't be done by drone helicopters and not be used for commuting. But the lathe of heaven turns

                  Electric passenger plane travel is coming , but not by quad copters. It is still as loud or louder than jet engines. Cargo by drone planes is going to be constant though. The sky will always be full of moving lights except in some dark sky preserves. I might retire near one just to stay sane.

          A bit of both. We can have really good passenger rail, but it is labor intensive over long distances.

            I live within the free public transport zone of my city, so I'm aware of short distance travel rail. If I want to visit family on the other side of the country, the cost calculations change (for now).

        Yeah but what if you want to visit another continent or live on island?

      Physically safest, yeah I'm sure. Just a couple years ago we went an entire year without a single airplane accident or crash, globally. Millions upon millions fly every year, and all those people travelled safely without a fatality, that's pretty dope.

      It sucks we aren't at a point where we can get people around the world while staying carbon-neutral yet. I guess when it comes to getting someone from one side of the globe to the other in a day, planes are the best we have for now.

      that sounds like a disaster waiting to happen on a number of levels.

    we need to return to hydrogen-powered zeppelins

    oh god no lol

    probably one of mankind's worst inventions, zeppelins have basically never done anything but horribly crash and kill people
