James Cameron has reached the deepest point in the ocean, the Mariana Trench, nearly 11km/7miles down using his custom made submarine “Deepsea Challenger”.  He made a solo descent taking two hours to reach the bottom.

This is only the second manned expedition to the ocean’s deepest depths – the first took place in 1960 with US Navy Lt Don Walsh and Swiss oceanographer Jacques Piccard.

Cameron’s craft may also soon be joined by other manned submersibles vying to reach the ocean’s deepest depths including Richard Branson’s DeepFlight Challenger, Google’s Eric Schmidt Doer Marine and Triton submarines, a Florida-based submersible company, intends to build a sub with a giant glass sphere at its centerpiece to take tourists down to the deepest ocean for $250,000 a ticket.
