It's only been a few years since humans could climb more than half a mile above the surface of the Earth without the help of jet fuel. It's easy to forget that buildings that reach this high into the atmosphere are a new phenomenon in our world—at these heights, it's more like aerospace engineering than architecture.

While photos of supertall buildings are all over the place, we rarely see the view from the top — images shot from their observation decks. I dug through Flickr's Creative Commons archives and realised there are plenty floating around out there, and they're breathtaking. Feel free to drop your own in the comments.
