Ahahah it is so so interesting.
I know you don't know why i am laughing.
This is because of result of my working;
the flat earth error has % 0,1 << %0,5 mathematichal error limit; and;
The sphere earth error has %0,1 << %0,5 mathematichal error limit
Ahahah it is impossible on a sphere world. I think somebody fooling us when they are creating a world map!
I got the images, files and excel file. This evening i will upload the values.
First I changed the airport Vnukovo to Sheremetyevo Int. Because there isn't fly to everywhere from Vnukovo Moskov but there is from Sheremetyevo Int.
I got all of distances from google map again by using Sheremetyevo Int instead of vnukovo;
I got all of distances from direct flyies by using Sheremetyevo Int.
