At the end of the article (scroll down) is the real payoff for me - wonderful sightseeing. I've flown across Greenland in daylight perhaps three times on four engine 747s. Let me tell you about it.
Greenland is huge; at jet speeds (ca. 550 mph) it takes an hour to cross east to west. For an hour you fly above an enormous ice sheet with rugged mountains poking up through it.
If you have a sunny day, the ice is blazing white and the mountains are a dark blue-gray. It is stunning. If the new rules mean more people will get to see these arctic sights, it is a real plus.
