While there was no reason for the guy to be snippy with you there are
a lot of folks who slide up and fly formation with the bombers without
talking to us before which raises a couple of issues. It is a
violation to fly formation with paying passengers, it is a violation
to conduct a formation flight without a pre-formation brief, and it's
not comfortable or safe to have every tom, dick and harry that thinks
he's a formation pilot coming up on your wing.

How close do I have to be to be "flying in formation"?
Yeah, I know.....FAA lawyers.
