The title says it all here, but this is ridiculous. The video was taken from the cockpit of a Royal Danish Air Force F-16 as it was flying, quite low, over an ice sheet in Greenland. There isn't too much information available, but after take off (hold on to your stomach) you'll first see the ice rim (located east of Kangerlussuaq, Greenland) and then you'll head over to the DYE-2 radar system and then over the icefjord (coolest word ever). After that, keep an eye out for the inspectionship Knud Rasmussen, which holds the title of the reaching the furtherst point north of any ship sailing on the west coast of Greenland (82°02'N, 62°01'W for the curious). This class of ship is built for extreme weather conditions (hence it's location.) The video ends after a flyby over the town of Ilussisat, where the namesake for the Knud Rasmussen class ships, polar explorer Knud Rasmussen, was born.
What's incredible about the F-16 Fighting Falcon--introduced as their go-to common strike fighter in 1980--is it's agility. Even though they've been modified and replaced since the late 90s, it's still a pretty amazing video.
