10x31 - Modern Marvels

Toxic traffic is everywhere! An average of 800,000 shipments of hazardous materials hit our highways and railways daily. From Wild West wooden crates filled with explosives to HAZMAT containers of nuclear waste, we shadow dangerous cargo. We ride shotgun on a hazardous material shipment that's tracked by satellites; hunt down the hush-hush "ghost fleet"–trucks carrying classified government materials; and board a Con-Air flight moving another kind of nasty stuff–dangerous felons!
