About ten years ago I saw a small plane, or large r/c go over my house. It had an internal combustion engine by the sound of it. I doubt it was big enough for a pilot, other than a feral test cat. It casually flew over my property, and out of pure instinct, I mooned it. Seriously. If anyone is using such a device to see what I'm doing in my backyard, government or civilian, they deserve to see my hairy pimpled azz.
