It comes in many deadly shapes and sizes, and the transportation of dangerous cargo is one of the most meticulously planned procedures in the shipping world. We hitch a ride on a "dynamite run" from explosives factory to construction site; learn how liquid natural gas is shipped, a fuel that could vaporize entire city blocks if ignited; accompany a Drug Enforcement Administration truck as it transports confiscated illegal drugs to an incinerator site for destruction; fly with Air Net as it moves radioactive pharmaceuticals from factory to hospital; and tag along with two tigers, part of a breeding program for endangered species, as they travel from Texas to Ohio. As each story progresses, we explore the history of the transport of that particular form of Dangerous Cargo.
