THE TITAN

Not Good

On September 18, 1980, at about six thirty in the evening, Senior Airman David F. Powell and Airman Jeffrey L. Plumb walked into the silo at Launch Complex 374-7, a few miles north of Damascus, Arkansas. They were planning to do a routine maintenance procedure on a Titan II missile. They’d spent countless hours underground at complexes like this one. But no matter how many times they entered the silo, the Titan II always looked impressive. It was the largest intercontinental ballistic missile ever built by the United States: 10 feet in diameter and 103 feet tall, roughly the height of a nine-story building. It had an aluminum skin with a matte finish and U.S. AIR FORCE painted in big letters down the side. The nose cone on top of the Titan II was deep black, and inside it sat a W-53 thermonuclear warhead, the most powerful weapon ever carried by an American missile. The warhead had a yield of 9 megatons — about three times the explosive force of all the bombs dropped during the Second World War, including both atomic bombs.

Day or night, winter or spring, the silo always felt the same. It was eerily quiet, and mercury vapor lights on the walls bathed the missile in a bright white glow. When you opened the door on a lower level and stepped into the launch duct, the Titan II loomed above you like an immense black-tipped silver bullet, loaded in a concrete gun barrel, primed, cocked, ready to go, and pointed at the sky.

The missile was designed to launch within a minute and hit a target as far as six thousand miles away. In order to do that, the Titan II relied upon a pair of liquid propellants — a rocket fuel and an oxidizer — that were “hypergolic.” The moment they came into contact with each other, they’d instantly and forcefully ignite. The missile had two stages, and inside both of them, an oxidizer tank rested on top of a fuel tank, with pipes leading down to an engine. Stage 1, which extended about seventy feet upward from the bottom of the missile, contained about 85,000 pounds of fuel and 163,000 pounds of oxidizer. Stage 2, the upper section where the warhead sat, was smaller and held about one fourth of those amounts. If the missile were launched, fuel and oxidizer would flow through the stage 1 pipes, mix inside the combustion chambers of the engine, catch on fire, emit hot gases, and send almost half a million pounds of thrust through the supersonic convergent-divergent nozzles beneath it. Within a few minutes, the Titan II would be fifty miles off the ground.

The two propellants were extremely efficient — and extremely dangerous. The fuel, Aerozine-50, could spontaneously ignite when it came into contact with everyday things like wool, rags, or rust. As a liquid, Aerozine-50 was clear and colorless. As a vapor, it reacted with the water and the oxygen in the air and became a whitish cloud with a fishy smell. This fuel vapor could be explosive in proportions as low as 2 percent. Inhaling it could cause breathing difficulties, a reduced heart rate, vomiting, convulsions, tremors, and death. The fuel was also highly carcinogenic and easily absorbed through the skin.
