Tourists can now book trips to visit the Titanic, the world's most famous shipwreck.
Deep-sea exploration company Oceangate is charging tourists more than US$100,000 each for a chance to join its planned submarine missions to the wreck.
"Citizen explorers" will board manned submersible operations - high-tech submarines. Explorers need to be over 18 years to be eligible for the trip.
More than 1500 people died when The Titanic sank in 1912, and more people have been to space than to the site of the wreckage.
The vessel - the largest ever built at the time - was found in two parts almost 70 years later in 1985 off the coast of Newfoundland, Canada.
Fifty-four tourists will dive, five-at-a-time, alongside a team who are attempting to fully document and create a 3D model of the wreck.
Each ticket will cost US$105,129 (NZ$150,875.88) - the equivalent of a first-class passage on the Titanic's inaugural sail, adjusted for inflation.
The model will be made using multi-beam sonar, laser scanning and photogrammetric technology.
