It's a bird! It's a plane! It's a ... Norwegian in a wingsuit? That's exactly what early risers in Rio de Janeiro saw - well, two Norwegians in wingsuits, to be exact - flying between skyscrapers in their metropolis. The two daredevils pulled off the unauthorized stunt at 5:45 in the morning to avoid air traffic. Watch the video at 1:13 as they approach and glide through the two skyscrapers. One unexpected wind gust could have been deadly.
