What Happened to the Biggest Animal to Ever Fly?

Описание: For millions of years, Earth’s skies were ruled by a creature so large it still feels impossible today. With a wingspan wider than a small airplane and a body heavier than any living bird, the biggest animal to ever fly pushed flight to its absolute limit. And then, it vanished.
This documentary explores what really happened.
Scientists once believed size alone should have made this giant unstoppable. But flight is a fragile balance between weight, wings, energy, and environment. As Earth began to change, that balance slowly broke. Shifting climates altered wind patterns and open landscapes. Large prey animals declined. Forests replaced wide plains. Every takeoff required more energy. Every landing carried more risk.
Unlike smaller flyers, this giant could not adapt quickly. It needed vast open spaces to launch, specific prey to survive, and stable conditions to stay airborne. When those conditions disappeared, survival became a daily struggle. Extinction did not arrive as a single catastrophe — it came as a slow squeeze, tightening with every environmental change.
This film examines the physics of giant flight, the ecological pressures that followed the age of dinosaurs, and why evolution eventually abandoned extreme size in the sky.
The biggest animal to ever fly did not disappear because it was weak.
It disappeared because the world changed — and flight has limits.
