I know a fair amount about aviation and it would be very hard to do with a plane all things considered. It would much easier to do in a a car than a plane. Better yet and real easy is to just to put governors (is that the right word) in cars so they couldn't go way over the speed limit but keep police type vehicles able to go faster. People would balk like crazy of big brother interference.
Getting back to weather 12Z GFS coming in is putting down some big rain totals. I will have image in a couple of minutes.
