Made this a few hours ago. It's the deepest drone I've ever made. Here's the story behind the name:
"Turkmenistan's aptly named Door to Hell, a 230-foot-wide crater in the
middle of the desert near the village of Deweze. In 1971, a team of
Soviet scientists set up a drilling platform looking for natural gas
reserves. The rig collapsed, and fearing the spread of poisonous methane
gas, the researchers set the crater on fire hoping it would burn out in
a few hours.
That was more than 40 years ago."
