Same here. I live in northern California so I have heard all the stuff
coming from Beale AFB and the Mach 3.0-3.5 range seems to be the
truth; however, the airframe of the SR-71 is stressed for Mach 4.0
flight. Maybe like the Foxbat this was for emergency only with
resulting damage to the engines and a/c. But I see little need for
such speed given the Blackbird's height invunerability.


What height invulnerability? It worked in the 60's but in todays
environment, there are quite a few missiles that could reach out and touch
the SR-71.

Well, there's "reach," then there's "reach with a decent chance of
hitting it."

The problem is that the few missiles with the height (80,000 feet plus)
didn't have enough targeting capability to hit the Blackbird at that
height, especially in a stern chase. The best they could do would be to
loft one up and try to get in the way.

The newer ones, like the "big" SA-20, might be able to do it, but it
would still be a fairly tough targeting solution - you'd need to loft
one up before the SR-71 was in range, then acquire it while in midair.
