LINK Apparently the U.S is banning billboards floating at low altitude atmosphere, close to space. But shouldn't it be some sort of international organization like the United Nations doing something like this? I like what they are doing, but as a matter of principal... does the U.S think they (or we, whichever) own space? And what do they mean "obstructive"? Isn't that like, an opinion? If they ban them, just ban them all!
