The "Devil's Cigarette Lighter," a natural gas well fire in Gassi Touil, Algeria that burned from 6 November 1961 'til 28 April 1962, shooting a flame eight hundred feet (800') into the air that was seen from orbit by John Glenn aboard the Mercury capsule Friendship 7; the flame was only extinguished when pioneering firefighter "Red" Adair & his crew used explosives to deprive the fire of oxygen.
