The Hindenburg Disaster: Probable Cause When the Hindenburg took to the skies in 1936, it was the largest flying machine in history. It was created when aeronautical engineering was a “new” science and the stresses involved in flight were not as well known as today. The cause of the Hindenburg’s tragic demise in only 34 seconds is still not clear. The documentary recruits specialist investigators to re-examine the airship disaster and look at modern airship technology for examples of where technology has advanced since the tragedy. Using blueprints held by the United States Navy and historical Civil Aeronautics Board charts that follow the Hindenburg’s route; the program re-creates the Hindenburg’s last journey and its ten successful voyages prior to the disaster

The future of stealth flight, including bombers that can travel at five times the speed of sound, brought to life through 3-D animation

Underwater archaeological research on the North Coast of Egypt reveals a site just outside the ancient city of Alexandria beneath the waters of Abourkir Bay. Also: the site of Cleopatra's sunken palace.

The strange notion of parallel universes is gaining strength in the scientific community and may solve our most basic questions about the universe, including the origins of the Big Bang itself.

Late Triassic Segment (220 Million Years Ago) The program starts in the Late Triassic, near modern-day New York City. The narrator explains how the Permian mass extinction led to new forms of life, including, eventually, the dinosaurs. The camera tracks a Coelophysis through the woods. The program decipts Coelophysis as preying mainly on small animals, such as insects and Icarosaurus. It encounters other, larger non-dinosaurs such as Rutiodon, Traversodon, and Desmatosuchus. Nevertheless, the quick Coelophysis is a very successful inhabitant of this world. Early Jurassic Segment (190 Million Years Ago) The program moves on to the Early Jurassic of Pennsylvania, showing a pack of Syntarsus. These dinosaurs, closely related to Coelophysis, are hunting for the primitive herbivorous dinosaur Anchisaurus, only to be driven away by a Dilophosaurus, which kills and eats the Anchisaurus. Late Jurassic Segment (150 Million Years Ago) The show skips to the Late Jurassic, where a pterosaur soars while a Ceratosaurus chases a Dryosaurus and its two young. The Ceratosaurus catches one of the juveniles, while the other Dryosaurus escape to the cover of a herd of Camarasaurus, feeding on the sauropods' conifer tree scraps that fall to the ground. The Ceratosaurus disturbs a Stegosaurus and gets whipped by its tail. Two Stegosaurus eventually mate. As the rainy season comes, a herd of Apatosaurus arrive, followed by a hungry Allosaurus. The Allosaurus cannot get past the Apatosaurus's whipping tails, but it manages to catch and eat the Ceratosaurus, still pursuing the Dryosaurus. Later, as the Apatosaurus leave the area, one Apatosaurus stumbles. Disabled, it is an easy meal for a small group of Allosaurus. Middle Cretaceous Segment (90 Million Years Ago) The program then shows a New Mexico forest of the Middle Cretaceous. Some coelurosaurs scamper through the forest, among frilled and feathered dinosaurs. One lone dromaeosaur [3] tries to attack a Nothronychus

Join paleontologist Jack Horner on a journey into the arid badlands of Montana where more T. rex skeletons have been uncovered than any other place on earth. Follow Horner – who found five T. rex dinosaurs here in a single summer – as he scrutinizes the T. rex's arms, large olfactory lobes, tiny eye sockets and unique teeth, to gain insight into whether T. rex was a ferocious predator or an opportunistic scavenger. For example, Horner surmises that the T. rex's stumpy arms wouldn't allow T. rex to scoop up prey, indicating he may have come along after the kill. Among Jack Horner's finds is the oldest T. rex ever found. At 68 million years, it's 3 million years older than any other specimen challenging the beliefs of when T. rex roamed the Earth. Also, see a 90% complete never before seen juvenile tyrannosaur called Daspletasaurus – an earlier large meat-eating cousin of T. rex. Visit dig sites, labs and museums, and witness brilliant computer animation that visualizes how these creatures lived and died. Plus, see new evidence that could allow scientists to reach ever further back in time.

This unique special looks at the whole phenomenon of giants from the earliest beginnings of civilization to the present. Also features interviews of Zecharia Sitchin, author of The Cosmic Code which talks about the content of the Sumerian Tablets. According to a scientist’s experiment on fish in a biodome with double the atmospheric pressure and a few other conditions, the fish grow to an unbelievable size which is proof that Earth had the right conditions back then to support the idea of Giants ever existing.
