Nah, I think you gotta be going pretty low and fast to do that. When I was
in grade school (gulp, back in the mid-60s) there was a local guy that was a
Navy pilot and he'd occasionally fly up over our school at recess time. And
he'd sometimes announce himself with a sonic boom. Not all the time, but
about half the time. All the kids thought it was great and it was a bit of
free PR for the military. Whatever altitude or conditions he did it under,
it was loud, but never enough to crack windows.

No, I mean the boom when they're coming in for a landing. I know that on
some orbital tracks the path brings them down across the Panhandle and over
the Gulf and then a curving path over central Fla. to land at the Cape. And
over the Panhandle they'd be actually somewhat lower (I think) than the
Aurora allegedly flies. Anyway, there's a characteristic double boom (don't
recall off hand the exact reason why it's double).

I hardly think they're going fast enough to go back in time... :-)
