Polar Routes
The first time we took a polar route from Toronto to Hong Kong, our flight veered left and we missed the North Pole by nearly 400 miles. Damn!
The next time, our flight veered just slightly to the right, and we were well inside 200 miles. Therefore within direct Line of Sight to the North Pole!! Yay!!
Conclusion: There's no giant 'North Pole' pole sticking up through the clouds. I've confirmed this personally.
