When landing a helicopter, I guess there are a few basic rules to follow. Make sure you don't land on people likely comes first, but a close second is probably to avoid landing near things that stand a good chance of getting blown away. This pilot didn't remember that part.
Apparently recorded in northwestern Libya, this video shows what looks like a Chinook landing at a festival. And in the process blowing over a giant marquee. I hope nobody got in the way of the metal frame as it landed. [jalparis004 via Reddit]
