Junker: Are you suggesting that pilots (and sailors) blindly follow their computer navigation systems to get from Point A to Point B and, in the meantime, don't actually have a clue where they are? Whether or not they have paper maps, in order to do their jobs properly and say, make an emergency landing in case of a storm, they need to know where they are at all times. I'm not sure why we're getting so caught up on this point.
SexWarrior: Wikipedia is firmly of the opinion that NK has nuclear weapons, and expresses no doubt as to that issue. The International Atomic Energy Agency shares that opinion. I haven't seen any sources that seem to doubt this, so I took that as an indication that it is well-known and well agreed-upon, at the moment. Nevertheless, this isn't even important to my argument. It was a throwaway comment meant to illustrate how many other nations have advanced technology among their higher-ups. I don't want to keep talking about this because it isn't important to my larger points.
And yes, planes and ships rely on maps that are based on a round Earth. They don't use globes, but they use maps which are projections of a round Earth. The distances you calculate on these maps are based off those that would be calculated from a globe. So yes, they are representative of RE.
