The world's worst air disaster happened more than 40 years ago on a remote Atlantic Ocean island, when two fully loaded 747 passenger jets collided after a horrendous series of human errors. One of the jets, KLM Flight 4805, was traveling more than 150 miles an hour and was within seconds of lifting off when it crashed into Pan Am Flight 1736 taxiing in its path. The loss of lives was staggering - 583 dead. The crash happened after a lengthy series of major and minor human errors. In the intervening years, has aviation advanced to the point that such a disaster can't happen again?

On the 100th anniversary of the Titanic's sinking, a prominent Titanic researcher offers a final chance to see the ship before it disappears forever. The Titanic was the biggest, most luxurious passenger ship the world had ever seen; the ads proclaimed it to be unsinkable. When it sank in April 1912 after hitting an iceberg, killing more than 1,500 people, the world was forever changed and the public has been spellbound ever since. Now, a century later, the Titanic is about to disappear again: its infrastructure is set to collapse in the next few years.

It is now six years since the secret disaster at Jurassic Park, six years since the extraordinary dream of science and imagination came to a crashing end - the dinosaurs destroyed, the park dismantled, the island indefinitely closed to the public. But there are rumors that something has survived.
