This might be the coolest thing you'll see all day.
This video, uploaded to YouTube shows two men flying in wingsuits over Rio DeJaneiro. According to the video's description, the daredevils are Ludovic Woerth and Jokke Sommer. The feat was made at 5:45 in the morning because they did not have permission to fly and did not want to disrupt air traffic. They landed at 6:05 AM.
