JF Ptak Science Books Quick Post
There have been several posts to this blog regarding unusual airport construction--covering part of the Thames, floating in the NYC bay, on top of numerous/differential rooftops, floating and/or moored in the ocean, on top giant airplanes, landing and launched from dirigibles, and so on (including a vertical airport where the aircraft are dropped in tubes). The example I have just found this morning is a mild twist on this topic, as it is a helipad--a futuristic one, judging from the Harley Earle/Buck Rogers-style design.
See, for example:

(There are other examples scattered around the blog--just check out "airports" in the Google search box for more.)
There is also a time/distance map of air travel originating from NYC:
