Air Force One Had to Intercept Some Inadvertent Flyers / How?

I have had the opportunity in the past to intercept some private planes in
restricted areas in the back of F-16's, and the goals of the fighters are to
provide mutual support, so the intruder is always kept in sight.

Also, F-16's have VHF radios as well, so they can communicate on VHF guard
if needed.

They will not fly as slowly as a Beech skipper, and even 160k is pretty
slow. Generally, being cut off by an F-16 should get the pilot's attention.
