An ancient civilisation revered by scientists for their extremely accurate calendars, the Maya are also known for their mysterious ability to predict unsettling events.

Great white sharks are the ocean's deadliest killers and as they swim closer to our beaches, attacks against humans are on the rise. MonsterQuest leads an expedition to examine why these monsters are becoming more aggressive predators.

Five thousand years ago man throws a handful of rocks into a campfire and stumbles upon a discovery that changes the world: Metal. Copper, Tin and Bronze empower the ancient world and allow empires to expand, armed with sharp, hard-wearing weapons.

Early man rubbed two sticks together and created fire. We learn to cook our food, saving vital energy. As a result, our brains expand. Armed with fire, we experiment by heating minerals to make tools allowing us to fight wars and build civilizations.

In a manoeuvre of strategic brilliance, Moses leads his people out of Egypt and lures the Egyptian army to a watery grave.

A tube system starved of investment, a lacking fire policy and an inadequate smoking ban were to have tragic consequences. In 1985, a series of disastrous decisions about safety procedures at Kings Cross station led to the death of 31 people.

The series finale focuses on the reliquary casket. Carl and Hamilton know the casket dates to a later period - probably early 15th century. Yet a series of engravings on it - the 'box code' - appears to make veiled references to Templar beliefs.

Chimpanzees are known to us as amusing circus attractions and are even popular as pets, but when they attack the results are frightening and horrific. Just as disturbing, across the US, witness reports suggest that chimpanzees may be on the loose.

Lost Worlds explores the tunnels beneath some of London's greatest buildings. The underground command centre from where the Battle of Britain was won is just one of the secret bunkers toured in this episode.

A single train crossing was the site of not one, but two disastrous auto collisions in a single year. How could this happen?

Megalithic monuments linked by electromagnetic energy. Prehistoric ruins arranged across distances in straight lines. Were ancient man's spectacular structures built by humans alone or do they bear evidence of design by other worldly visitors?

Why did Asiana flight 214, packed with passengers, suddenly crash land and cartwheel across San Francisco International Airport's runway? Three families of the dead want answers.

The Romans, with the greatest army in the world, are annihilated by Germanic tribes at the Battle of Teutoburg Forest. Go inside the culture of some of the most famous warriors to explore their weaponry, tactics and, ultimately, their psyche.
