I love the Reddit thread about this cartoon. Comments range from “Hilariously unfunny” to “Also, why 56 hours? A geostationary orbit is (theoretically) possible at 22,236 miles above the Earth’s surface, so a 56 hour journey would have an average speed around 400 mph. I would think it would be possible to accelerate to much higher speeds than that, at least on the downward journey.“
