Aerial footage of the second largest man-made hole in the world, the Mir Mine in Russia.

The video, filmed in Mirny, eastern Siberia in March this year, shows the former diamond mine, which is more than 500 metres deep.

According to the filmer, you can't fly directly over the mine because there have been reports of helicopters getting sucked into the hole by the airflow.
