Getting anywhere on Earth in an hour isn’t difficult, there’s just not much reason for it, but the tech is easy enough. Anything that can get to space can land anywhere real quickly.
And from a human-rate standpoint, it’s a bit harder but simply isn’t economically feasible. Who’s gonna pay millions of dollars for one 30-min flight from DFW to Tokyo? Where you’re strapped down like an astronaut with no training, on a loud, annoying rocket trip?
Sure, millionaires might do it to say they did, but it’s not gonna be a daily flyer for anyone.
Landing safely is the actual trick.
