Ha ! I know you meant this as somewhat of a joke, Bob - but ... it
may not be that far off.
I would say that the frequency of it was around 100 Hz and very
constant - unlike anything in nature and no Doppler.
Because of McClellan AFB (which would have been the destination)
we do get the occasional sonic boom here, as the ocean lets it
reverberate for quite some distance - and they are prohibited from
going supersonic over land - but even 50 klics offshore it can be
very loud when conditions are right.

... what did you say the frequency of the Aurora pulse-jet is?

DON'T PANIC
It was merely Aurora's PDE on it's return flight to Groom Lake
after getting the latest MASINT on Iran:

We'll speak to the pilot since he was clearly a bit out of the
envelope on approach.
