In a previous article, (Robert M. Gary) said:
Does anyone know the actual reason you're required to file a flight
plan when crossing the boarding between the U.S. and Canada? Does

Because if you don't, they'll send a pair of F-16s out to check you out.
And then, if they decide not to shoot you down, they send you a bill for
the fuel the F-16s used. You don't want that. :-)

That just doesn't make any sense though. If you are talking to ATC,
they would just ask you what you are doing. Remember though, there is
no ADIZ between Canada and the U.S. If you decide not to talk to ATC
as you cross you wouldn't have a transponder code so they can't tell
the difference between the planes that have filed and those that have
not. They all just look like dots on the radar. How would they know
the difference? When you cross the ADIZ (like from Mexico), you get
your own code and everything, its very different.
