re: hangars
If you manage to rewrite objective reality, I'll be the first to admit I'm wrong about things. But various people have been claiming to be able to do this for a couple of thousand years now, and somehow the mundane physical world rolls on pretty much unobstructed by astral traffic, teleporters, psychokinetic construction teams, aliens on the White House lawn, or anything else along those lines.
Really, the "mundane" world isn't all that mundane just the way it is. And from my point of view, a little black piece of plastic the size of a postage stamp that contains a computer that would have filled a building when I was a kid, is magic enough for me!
