I've read that the U2 (or is it U-2) has a 4 knot speed range at altitude.
Too fast, you get mach buffet-too slow, you stall.

It's U-2... U2 is a leftist Irish rock group that thinks that just because
they're made a few songs that people like, their opinion on world matter
actually means something... Kind of like actors in that respect, I guess...

The original U-2 had a rather small range while at altitude between stall
speed and mach buffet... Especially in the U-2A through U-2C... The latest
of the series are the U-2R and U-2S models and from what I've heard, some of
the bad characteriestics from the eariler models were improved upon...I
believe that there is now an 8 kt speed range... Originally it varied from 3
to 5 kts...

And interesting tidbit of information is that the U-2G model was made for
carrier operations and actually took off and landed from the USS Ranger back
in the early to mid 1960s...
