The worlds biggest hole is located in Russia. The giant hole is actually a diamond mine in Eastern Siberia near the town Mirna. It is 525 m deep , and 1,25 km. in the diameter.

This loader is one of the biggest in the world : length : 13,36 m width : 7,78 m height : 6 ,65 m This giant machine appears just a small point in the next image.

Az árok fölötti légtérbe tilos berepülni, mivel korábban történtek itt helikopteres balesetek, mert a szívóerő egyszerűen beszippantotta a helikoptereket. The suction above the hole resulted in several helicopter crashes, so all flight above the hole now is prohibited.
