For Blackbird fans, the Intrepid museum in New York (https://en.wikipedia.org/wiki/Intrepid_Sea,_Air_&_Space_Muse...) has a real one on display; technically it's an A-12, the reconnaissance version. That's in addition to a Concorde, that you go over :) and a space shuttle that you can't :(

Perhaps it was due to the aircraft's larger-than-life reputation, but the real thing was rather smaller and must less striking that I was expecting :(
