"We have never had an accident that resulted in a release of radio-activity from one of these trucks or in any damage to the cargo in these trucks."
Air Force documents show that pilots transporting nuclear weapons today are told to avoid flying over heavily populated areas to the maximum extent possible. General D.H. Cassidy of the Military Airlift Command praised the "bully beef express" for its outstanding safety record in an internal memo last year. But he also warned the crews about complacency after Air Force personnel mentioned on a non-secure telephone the nature of the cargo on two nuclear weapons flight. Military Airlift Command Regulation No. 55-141 tells the crews how to respond to a hijacking attempt. "Never allow a hostile force to capture or control a nuclear weapon," it says, "even if it means risking the lives of any hostages that might have been taken." The regulation instructs the crews on when to use CDS—the command disable system, which is attached to some nuclear weapons. "CDS," the regulation says, "internally destroys the capability of a weapon to achieve a significant nuclear yield." "As a last resort," the regulation says, "nuclear weapons must be destroyed even if it means loss of the aircraft.
The department of Energy says it too takes great precautions against accidents or terrorist attacks. Spokesman Ben McCarty says the trucks that haul nuclear weapons across the country have armor-plated cabs. The drivers are trained and equipped with a number of firearms, and the trucks are escorted by additional armed guards in cars. Ben McMarty, "We know where all the trucks are at all times, and we have both voice and data links to them. And should anything happen to the shipments, the escort vehicles are able to communicate immediately with local or state law enforcement people and the full force of the military establishment should it be required."
