Base jumping, one of the world's most dangerous sports, is very cool. The Burj Khalifa AKA the Burj Dubai, the world's tallest building, is also very cool. The two together? Well that's just God damn crazy.
See that little speck falling off that building? That's either Nasir Al Niyadi or Omar Al Hegelan, two extremely extreme extreme sports dudes, flying all 2,716 feet down the side of the recently-opened Burj Khalifa, the world's tallest building.
Head over to The Guardian for video of the amazing feat.
The video includes helmet-cam footage of the world record-setting, half-mile drop. One of the jumpers moments before taking the plunge: "You're still looking at us like we're crazy." Uh, yeah. [The Guardian via @designobserver via Fast Company]
