What gives jet airplanes, which have been known to reach the size of office buildings, the ability to leave the ground? It isn’t rocket science—although that’s also covered in this high-energy program on the complexity of flight. For basic training in aerodynamic principles, viewers take an exhilarating hang-glider ride and venture inside a high-tech wind tunnel used by Olympic ski jumpers. Next up: the launch of a mammoth homemade rocket, the centrifuge tests that jet pilots undergo to fight the effects of high G-forces, and the wonders of parabolic flight—which briefly simulates weightlessness. Finally, the program gets up-close and personal with the only mammals capable of actual flight: bats. (22 minutes)
