In 1912 Titanic departed on her first and last voyage from Southampton, sinking over 2 miles to the bottom of the dark North Atlantic Ocean, around 400 miles off the coast of Newfoundland. It has captured the imaginations of adults and children alike for over a century since the wreck was discovered- broken in two, but largely intact by explorer Bob Ballard in 1985. Since then, people from all over the world have been desperate to see the slowly degrading wreck on the ocean floor, some paying in the hundreds of thousands to make the trip down.

Currently, the world watches as organisations and countries work together to try and locate a submersible carrying tourists that disappeared in the early hours of an expedition on Sunday. Titanic expert Tim Maltin joins Dan to talk about Titanic tourism, what the perilous journey down to it is like, the state of the wreck and its role as a gravesite for those who perished in the sinking. He also describes the astonishing things Bob Ballard saw when he laid eyes on the wreck for the first time - the swinging chandeliers and the telephone set from which the final distress calls were made compared with what people might see today.

Produced by Mariana Des Forges and edited by Dougal Patmore.
