As an interested layman I'd have thought, the higher, the better, because less friction. Now I'm wondering why. Because of lower outside air temperature, making some material expand/shrink too fast? Now I'm puzzled. Does this mean it can't go (high) supersonic at lower altitudes either? Because denser air causing even more friction? I mean something like Mach 2 at 1000 feet. Mission impossible?

> What is their opinion about being unable to go supersonic for more than short bursts currently classified as "will not fix"
Those two countries do not do carrier ops, why would they care about this at all?
A hint they got from the world of software development clearly... :-)
"...At extremely high altitudes, the U.S. Navy and Marine Corps’ versions of the F-35 jet can only fly at supersonic speeds for short bursts of time before there is a risk of structural damage and loss of stealth capability, a problem that may make it impossible for the Navy’s F-35C to conduct supersonic intercepts...
The Defense Department does not intend to field a fix for the problem, which influences not only the F-35’s airframe and the low-observable coating that keeps it stealthy, but also the myriad antennas located on the back of the plane that are currently vulnerable to damage, according to documents exclusively obtained by Defense News...
...The F-35 Joint Program Office has classified the issues for the "B" and "C" models as separate category 1 deficiencies, indicating in one document that the problem presents a challenge to accomplishing one of the key missions of the fighter jet..."
