" Mirny Diamond Mine , Serbia
It's the largest open diamond mine in the world. At 525 meters in depth, with a top diameter of 1200 meters, a no-fly zone is imposed above the hole due to a few helicopters having been sucked in."

That's pretty strange. I've never heard of a helicopter getting sucked into a hole before.
