North Korean arms shipment intercepted

Imagine you're smuggling arms out of North Korea and don't want to put rocket propelled grenades on the manifest. What would you list? Maybe pickled cabbage or craft goods, but certainly not "oil drilling equipment". And you might want to prearrange fuel stops for your aircraft rather than have to make an "emergency request to refuel" enroute to your destination. Such are the circumstances in which a chartered plane carrying 40 tons of North Korean arms has been seized in Bangkok. Not geniuses these guys.
