Yes the American hanger at Duxford is great. The B52 bomber in there is massive! The plane takes the whole width of the hanger.
Quick nerdy fact about the Blackbird (SR71)
When stationary the fuel tanks leak, only when it's flying do they not, this is due to the heat generated when flying at Mach 3 by the air passing over the wings causes the metal tanks to expand and make a tight seal!
