Supernature - Wild Flyers S01E02 - Masters of the Sky

In this episode we see how nature has pushed the basic flying body plan to extremes. How do the heaviest animals take off, the fastest use speed as a weapon, or those traversing the widest oceans do so with barely a wing beat? All these record breakers push physics and physiology to the limit, but although each one employs a different aerodynamic mix of speed, maneuverability, endurance and power it allows them all, in their own unique way, to become true masters of the sky.
