Violating Airspace with GPS

CJ,

Thanks very much for the response. Your perspective is very illuminating
and confirms many of my suspicions and observations.

I often fly over near Washington, D.C. I can't tell you how many times that
I have heard the authorities trying to raise an aircraft that has violated
the Washington ADIZ on 121.5. The same aircraft that is violating the
airspace are usually not monitoring 121.5. Usually, it is a futile
broadcast in the blind. In fact I have never heard a response from an
errant aircraft.

Thanks everybody else for your responses also.
