Planes don’t usually reach the limits, but they exist. The limits seem to be 1200mph or 59000ft altitude.

Unfortunately many cheap GPS chips use the (incorrect) or definition, not and. It was a pain to find one that works above 59000ft but very slow speed for a weather balloon project some years ago.
