Your average metropolitan airport is on a desolate tract of land far from the city's center. But that doesn't mean past urban designers didn't try to incorporate airfields into cities' layouts. Here are some fanciful urban aerodromes of yore.

John Ptak at Ptak Science Books has done a round-up of past urban airports. Some of them are hilariously impractical (not to mention downright dangerous), but hey, all of them beat paying out the nose in cab fare.
