Stash: "Based upon what evidence?"
Nature realities don't allow such flight to exist. It's like 'moon landing' which is dismissed by nature realities:
- dome wouldn't give possibility for any spacecraft to go beyond its body - unless there is door(s) on the dome.
- moon material is transparent >> blue sky color can penetrate it. So moon ain't a place like earth. It's just a body with shield AKA dome.
The same reason applies for the non-existence of 'crossing north pole flights'.
As I said before, globe belief has existed for ages, but no flight has followed such belief from the beginning of flights up to lately.
With respect to globe belief, there should have been flights crossing the north pole since the beginning and they'd never go with existing routes. In fact it's not been the case. Existing routes are still implemented.
I understand what you believe to be as "nature", but you have no evidence for the "nature" you speak of. For example, a dome. There is no evidence for one found by anyone, anywhere, ever. However I have actual evidence that the north polar region does exist. I think this has been brought up before, but a very recent example of evidence is that Air India started fights from Delhi to San Francisco just last week. Others have flown it before, but a first for Air India as a commercial route.
"Marking a new milestone, Air India has operated its flight over the North Pole on Indias Independence Day and has become the first Indian airline to operate commercial flights over the polar region. The flight from Delhi to San Francisco usually flies over the Atlantic or the Pacific Ocean but on 15 August, it flew over zero degree north."The flight looks something like this:
So I respect your belief system, but also need to respect the evidence. And evidence shows a navigable north polar region on earth, not an unknown, unobserved dome impeding the route.
