66 million years ago a seven-mile-wide asteroid collided with Earth, triggering a chain of events suspected of ending the dinosaurs' reign. But experts have long debated exactly what happened when the asteroid struck and how the giant beasts met their end. Now, scientists have uncovered compelling new clues about the catastrophe - from New Jersey to the wilds of Patagonia, and an international expedition of scientists has drilled into the impact crater off the coast of Mexico, recovering crucial direct evidence of the searing energy and giant tsunami unleashed by the asteroid. Join NOVA as scientists piece together a chillingly precise unfolding of the Earth's biggest cataclysm, moment by moment. And discover how our early mammalian ancestors managed to survive and repopulate the Earth.

The World's Longest Motor Journeys Long distance car rallies, including the London-Sydney and the Pan African rallies, and attempts to drive round the world (by Kegresse half-tracks in the 1920s) and the length of the Americas. Epic footage of speed and endurance. With the development of the motor car man soon turned his attention from using it as a means of travel to using it for his sporting aspirations, to driving around the world, to remote corners, to those places where few men have ventured before. Driving in these early days was always a challenge. Dirt roads that the horse found perfectly acceptable became impassable quagmires of mud for the automobile. Despite these challenges, it was not long before the automobile transformed itself from novelty to necessity. The advent of the world's longest motor journeys took place with the London-Sydney and Pan Africa car rallies, in deserts and at tropical jungles. These were then followed by epic attempts of endurance to drive round the world and across the length of the Americas.
