We often hear the old 'SR-71 was replaced by the satellites' arguament- but, as ane fule no, the orbits are soooo predictable.
The need for a top line recce a/c has never gone away- so if the US simply abandoned the requirement (or went back to the previous one) - it would be quite a big deal.
Anyway, try getting into Area 51 to check!
