IET has a single, coherent map.
It does? Can we see it?
What makes the Greenwich meridian the correct center for a flat earth map? Where would you end up if you followed it north as in your OP?
I don't believe the Greenwich meridian marks the centre of the earth. I think it's a bit east of that, running through East Africa. I believe this as this is where the first humans started, and we migrated out from there.
"I don't believe..." "I think..." "I believe..."
This doesn't sound very convincing that what you're proposing is the
one true map. This sounds like you're describing the "bipolar-flat-earth" map centered on a longitude somewhat east of the Prime Meridian and, presumably, the equator (but you don't say that). The problem with this is the shortest route from Honolulu to Tokyo would be eastward, over North America. You may want to check, but I don't think airline or shipping companies go this way; they seem to think going
west from Oahu to reach Japan is faster.
And it works - you don't get magically transported across the world, unlike your globe.
Why does anyone need to be "magically transported" to go from any point on the globe to any other? I suppose to someone from the 19
th Century, a jet airliner would be a "magic transport", and since flat-earth ideas seem firmly rooted there, there's that. Nonetheless, it's not
required to travel by jet, it's just
very convenient and can be very inexpensive considering what you get. Jet travel might
seem like magic (especially in First Class), but it's
not magic.
