Detailed explanation-1: -Hollywood director James Cameron has returned to the surface after plunging nearly 11km (seven miles) down to the deepest place in the ocean, the Mariana Trench in the western Pacific. He made the solo descent in a submarine called Deepsea Challenger, taking over two hours to reach the bottom.
Detailed explanation-2: -Backed by a team of scientists and engineers, Cameron spent seven years building a submersible capable of reaching the deepest point in the ocean, seven miles below sea level.
Detailed explanation-3: -Don Walsh and explorer Jacques Piccard sit inside the Trieste, the submersible they used to descend to the Challenger Deep-the deepest spot in the world’s oceans-in 1960. The feat was not repeated again until 2012, when movie director James Cameron returned to the same spot in a small submarine.
