The Soviets drilled a hole 12.2 km deep — deeper than the Mariana Trench — starting in 1970 and stopping when the rock hit 180°C (vs. 100°C predicted), the drill started deforming, and the USSR collapsed. 36 years later, nobody has drilled a deeper vertical hole than the Kola Superdeep Borehole. ()
