I have a friend, an aerodynamicist with a PhD, who states clearly that no
prop tip ever goes supersonic, as that would make it unable to perform its
task. I'm not so sure I believe him, though. There's very l little else that
would account for that noise. Once heard, never forgotten.

Perhaps because it has a small prop whose tips go supersonic, Bill? If it
has a prop with a small area, perhaps it has to go faster to create
sufficient thrust.
I'll ask someone who might know, at work.
