Summary

In 2002, the discovery of a unorthodox fossil reignited the debate over the origin of flight. With four wings and preserved feathers, the 130 million-year-old creature was like nothing paleontologists had ever seen before. This documentary visits the Chinese stone quarry where the fossil was discovered as the world's leading figures in paleontology, biomechanics, aerodynamics, animation, and scientific reconstruction perform an unorthodox experiment - a wind tunnel flight test of a scientific replica of the ancient oddity.
