This website exposes the flat earth deception and proves that the earth is globe shaped.
Wolfie6020 posted this video about the Creating Flight Plans for Flat Earth app that is available @ http://walter.bislins.ch/bloge/index.asp?page=Creating+Flight+Plans+for+Flat+Earth
This APP is not to be used for real world navigation. Because the Flat Earth does not match the real world.
The app produces a flight plan that would be correct if the Earth was Flat.
It is a valuable tool for testing various routes and comparing them to reality.
The flight plans calculated for a Globe will match reality.
Flight plans calculated for a Flat Earth will not.
