Today, the railway still ferries valuablecargo across the Canal Zone including curious day-trippers on jungle-thick journeys past man-made lakes, locks and causeways.
In the decade through 2002, armed robbers staged at least 10 major heists on the tarmacs of European airports, and robbers who didn't pull guns executed many more thefts of cash, diamonds and other valuablecargo from high-security areas, according to airport-security specialists.
People handling airfreight are aware of valuable consignments because every cargo shipment carries a waybill, which is similar to a passenger's boarding pass.
