I missed 5, and sadly one I missed was The Alamo, which I have seen from the ground a number of times.
I also missed the Cape Canaveral launch pad, and we lived a few miles from there for 3 years. Never saw it from the air, though. There are several launch pads, and only one is shown, but I'm sure it wouldn't have helped to know which.
Thanks for the interesting link!
