OTOH, nobody who knows how high a U-2 can fly is telling.
No doubt. But it has been declassified that the original RFP for the
U-2 requested the ability to fly at 70,000 feet. So while it may be able
to fly higher than that, I would not expect that it normally flies _much_
higher than that, even when doing reconnaisance.
One can fly almost five times as high - 67 miles high - if one is flying
an X-15. And thenthere's the Space Shuttle. So, indeed, there are things
to fly that would fly higher.
And if they still aren't talking about how high a U-2 can fly, then accurate
information about the altitude of an SR-71 Blackbird would be even harder
to find, but as the pilot is provided with an oxygen mask designed to allow
flight at 80,000 feet, it _seems_ as if it might be just the airplaine you would
want to fly if you want to look down on a U-2.
