listings as dates and times may vary.

In 2002, the discovery of a beautiful and bizarre fossil astonished
scientists and reignited the debate over the origin of flight. With
four wings and superbly preserved feathers, the 130 million-year-old
creature was like nothing paleontologists had ever seen before.

In this program, NOVA travels to the Chinese stone quarry where the
fossil was discovered -- a famed fossil treasure-trove -- and teams
up with the world's leading figures in paleontology, biomechanics,
aerodynamics, and scientific reconstruction to perform an unorthodox
experiment: a wind tunnel flight test of a scientific replica of the
ancient oddity.

Here's what you'll find online:
