Soviets Use a Nuke To Put Out A Fire

In 1966 the former Soviet Union suffered blowouts on five natural gas (methane) wells and despite their best efforts, including hydraulic fracturing, were unable to quench the flames. The Soviets lowered a specially made 30 kiloton nuclear bomb into a 6 kilometers (20,000 ft.) borehole. The nuclear explosion took 23 seconds to put out the fire.
