Back in May, two thrillseekers sneaked into the Burj Dubai — currently the tallest building in the world even though it's not finished yet — and set the world base jumping record (illegally). The footage of the jump from the top is worth a watch by itself, but the story of the pair's experience makes it even better. It's the kind of stunt reminiscent of high-wire walker Philippe Petit, who infiltrated New York City's World Trade Center towers so he could walk on a rope between the two.
