Siberian Internationale
Legend has it that a team of Soviet engineers led by "Mr. Azakov" drilled a 14.4 km deep hole in the facility Kola Superdeep SG-3, placed on Kola peninsula in Siberia before reaching a cavity. Intrigued by this unexpected discovery, they lowered an extremely heat-resistant microphone and other sensory devices into the borehole. The temperature at this depth was 1,000 °C, and the heat emanated from a fiery chamber from which screams could be heard.
Soviet scientists drilled into the hell!
The sounds they recorded in the depths of hell can still be found on the internet today:

But that wasn't true! In fact, in the bowels of hell, they recorded THIS:
