Egypt's Great Pyramid may be humanity's greatest achievement: a skyscraper of stone built without computers or complex machinery. This super-sized tomb has fascinated historians and archaeologists for centuries, but exactly how the ancient Egyptians finished the monument and fitted its two and a half million blocks in a quarter of a century has long remained an enigma. Today the secrets of the pyramid are finally being revealed thanks to a series of new findings. At the foot of the monument, archaeologists are uncovering the last surviving relic of the pharaoh Khufu, whose tomb it is: a huge ceremonial boat buried in flat-pack form for more than 4500 years. It's a clue that points to the important role that ships and water could have played in the pyramids' construction. This documentary follows investigations that reveal how strong the link between pyramids and boats is. It's a story of more than how Egypt built a pyramid: it's about how the pyramid helped build the modern world.

The sinking of the Titanic was far more than a simple accident. It was a tragedy that could have been prevented. It was the result of a long chain of mistakes: a fatal series of avoidable human errors that sent the Titanic and more than half of her passengers to their watery graves. Based around the official inquiry held immediately after the event, plus evidence that's come to light since the wreck of the Titanic was discovered in 1985, National Geographic, in this drama-documentary special, answers the question: Who Sank the Titanic?

On April 10, 1912, the RMS Titanic embarked on its maiden voyage, sailing from Southampton, England, to New York City. One of the largest and most luxurious passenger liners at the time, the Titanic was also equipped with watertight compartments, which led many to consider the ship unsinkable; an anonymous deckhand famously claimed that “God himself could not sink this ship.” On April 14, however, the ship struck an iceberg, and early the next day it sank. Some 1,500 people perished.
