By coincidence, one came through RAF Wyton today, Chuck: a Spitfire I
mean. It sounded lovely, but we reckoned that he was treating the
engine carefully and had it throttled a fair way back. But the shape
is lovely to see as well as to hear the engine.
These "maximum speeds" mean very little. Even if you assume a
standard atmosphere for the temperature and pressure at the height
mentioned, each aircraft and engine will have different
characteristics - and I am very suspicious of seemingly exact numbers
like that. They are only really useful for young (and old :-)) boys
to compare when playing games.
437mph could of course be the maximum allowable air speed, but that
doesn't sound likely either.
