Earlier this month, the filmmakers of the new documentary series "Frozen Planet" caused quite a bit of penguin pandemonium on the web with a video of two penguins in flight -- as passengers on a plane, that is. Now, the filmmakers have released another clip of the birds soaring through the air, and this time they're using a very different flight method. In the video, female emperor penguins propel themselves through the water and rush through the surface in a short burst of flight.
