'I saved for 30 years to see the Titanic'

For 110 years, the Titanic has sat at the bottom of the North Atlantic, and seen only by a handful of researchers and explorers.

Since she was a child, Renata Rojas has longed to see the wreck of the famous ocean liner which sank on its maiden voyage in 1912.

However, some travellers are now paying up to $250,000 to see it.

For the first time, the BBC follows some of these "citizen scientists" who have paid for one of the scheduled dives by American company Oceangate.
