Tight Slot,
Plenty of asphalt runway at Sonde Strom: 9235 x 200 feet.
SFJ is a major hub for flights within Greenland and there's a modern hotel, quite large, on the civilian side of the airfield. USAF facilities on the other side have been cut back severely, I believe.
It's a scenic spot, where you can see reindeer, arctic hare, and off in the distance, the Inland Ice, plus interesting geology - I can think of worse diversions.
