At the moment Voronya Pestera is the deepest cave on earth. The height difference inside the cave is 2,140 m, which is much deeper than the Grand Canyon.

This cave is unfortunately located in an unstable and more or less lawless part of the world, in the Western Caucasus in Georgia, a former Soviet Republic. This made it almost impossible for foreign cavers to visit this place in years. Even the locals have some difficulties in exploration, especially poverty and the impossibility to get the necessary equipment.

In early January 2005 an accident happend, and a helicopter with cavers on board crushed at the cave. The helicopter brought cavers and material when it kicked up a lot of the powdery snow at the landing spot. The pilot could not see the mountain any more and the rear propeller hit the side of the mountain. The helicopter started to spin on its own axis, three cavers fell out of the rear door and hit the soft snow 10 m below. Finally the helicopter grounded. There were no casualties, but the three cavers who fell out and the pilot were injured. Some equipment was damaged and the expedition was aborted.
