What is all this noise about? We have been flying across the pole since the days of Astro, Loran and Doppler. Yes that was before INS, before IRS and before GPS. We've been flying into India from the north from the moment we could cross the mountains between Samarkand and Dushanbe over Kabul to Lahore. Even the distance is not extreme anymore since the advent of the 744 well over ten years ago.

So what is new? :confused:
