I was always under the impression that filing a flight plan for every flight is an excellent idea, and greatly assists with any SAR effort, when you disappear off the radar, or don't turn up at your destination.
Dick obviously thinks flight plans are an anachronism, and everyone should be able to just jump in their bugsmasher and tool around the sky, blithely darting here and there, and dropping into airfields at whim, just to keep ATC on their toes.
Is the U.S. aviation scene so much safer, because their systems are so much freer and better?? Inquiring minds need to know.
