This society is about the search for knowledge. What is a latitude? What is a longitude? How was it originally calculated in relation to the celestial bodies, and what does it mean? What do latitude or longitude the formulas used in relation to the moon mean? What must it mean?
If you are to profess knowledge and truth then you should be expected to show and demonstrate knowledge of the coordinate systems used, the types of maps used, the jet streams, the nature of north and south and east and west, the
admitted increase of time to flight times, the available routes, and knowledge of those which may be unavailable, as was mentioned by iampc above.
We all want to be educated on this matter. Unless you can teach to any reasonable thinking person, of how all of this works, then you have
no knowledge.If you happen to come to the conclusion that you have
no knowledge, then you should admit as such, and then seek to know what you do not know.
"They must know..." is not enough. Show. Demonstrate. Tell us, so that multiple different people, even if I am excluded, may look at your information say that it is clearly the correct answer and all is unanimous. We have provided that platform for you here, and allow all to participate.
