Has anybody ever been issued a citation based on their speed being monitored by aircraft? I see the signs out on the freeway but always have guessed that they're just for show.
Yup, way back in college (late 80's). They had several cops lined up just coming into town picking students up coming back from break. I'm sure they made a pretty bundle on that. The aircraft times you in between markers on the freeway, calculates your speed, then radios the information to the cops on the ground.
Every time I drove back to college after that I looked for that damn airplane and actually saw it once. I drove like a grandma the entire way into town and sure enough, they had the same setup with a bunch of cars pulled over coming into town.
