You may not have seen anything like this close-up, an unmanned aerial vehicle taking pictures of a fire pit called the "door to hell" in Turkmenistan that could reach temperatures of 1000 degrees Celsius (1830) Fahrenheit
The 69-meter-long hole, 30 meters deep, was formed when a group of Soviet engineers were exploring natural gas sources, opening the mouth of hell.
Fearful of the release of dangerous gases in the atmosphere, they set the fire on fire in the hope that it would burn within a few weeks.
Obviously they did not succeed
Burning has not stopped since that day in 1971 and has become a major tourist attraction for the low-density area of Drwiz.
