Being that you mentioned flying authorities...

I was once cited for "buzzing," and was contacted by a Pennsylvania State Trooper... they investigate aviation incidents.

The trooper gave me the choice of meeting him at the police barracks, or he come meet me at my home.

I knew, through a friend, that he was also a pilot, and I was building an experimental plane (BD-4). So, I thought he might be interested in my project, and invited him to meet me at home.

He definitely was interested, and we spend a couple pleasant hours swapping airplane stories and drinking coffee.

As he was leaving he remarked "If you're gonna buzz someone, do what I do. Buzz them, and get the hell out of there. Don't make a second or third pass, drawing a crowd."

Good advice. I ended up being fined $60, but at least I wasn't temporarily grounded!
