ORAC & jimgriff,
I hear what these folk claim; nevertheless, such absolute heights and speeds are pretty dramatic. The fast moving Lightnings I pointed upwards, or allowed to run, or both, never showed any potential for attaining such parameters.
My recall of the OR946 Height Display specification is a little dim, so I cannot remember what, or if there was any upper limit on the height it could display. My English Electric T5 Prototype Pilots Notes do not go into such detail! However, I doubt that the air data system was calibrated for such low ambient pressures.
Time for Tarnished to offer a view?
