The sky is a crowded world where mammals, birds and insects hunt, escape, mate, defend territory, sleep, and even die on the wing. Survival up here depends not just on beating gravity or mastering flight, but also out-flying the competition.
Many animals take to the skies for a split second, but to stay there the planet’s strongest flyers have to push the laws of physics right to the edge. Explore the extremes of true flight: Power, acceleration, top speed, maneuverability and endurance.
How do animals take to the air in the first place? Each of the incredible creatures we’ll meet has its own special techniques. But they must all overcome one of the planet’s most powerful and universal forces – gravity.
