How The CIA Engineered a Three-Kiloton Siberian Pipeline Explosion
A fascinating Cold War story by William Safire:
Instead, according to Reed - a former air force secretary whose fascinating Cold War book, "At the Abyss," will be published by Random House in March - Weiss said: "Why not help the Soviets with their shopping? Now that we know what they want, we can help them get it." The catch: computer chips would be designed to pass Soviet quality tests and then to fail in operation.
In our complex disinformation scheme, deliberately flawed designs for stealth technology and space defense sent Russian scientists down paths that wasted time and money.
The technology topping the Soviets' wish list was for computer control systems to automate the operation of the new trans-Siberian gas pipeline. When we turned down their overt purchase order, the KGB sent a covert agent into a Canadian company to steal the software; tipped off by Farewell, we added what geeks call a Trojan Horse to the pirated product.
"The pipeline software that was to run the pumps, turbines and valves was programmed to go haywire," writes Reed, "to reset pump speeds and valve settings to produce pressures far beyond those acceptable to the pipeline joints and welds. The result was the most monumental non-nuclear explosion and fire ever seen from space."
