458 pages, is a northern route, still possibility?
Well I think so.
Many accept so easily that one country did not respond to an unidentified aircraft crossing their borders and overflying their territory, and not letting on until days later, but only a few accept the possibility of a nothern route.
What is the intersection of the satellite - ping flight path and the Nothern arc? What are the countries that would have to be overflown?
There is also nothing to say that these countries need to publicize instances of unidentified aircraft crossing their borders. In fact there are many good reasons why they cannot.
I am trying to help. Check the northern route.
