In 1960 two men went to the bottom of the Mariana Trench in the Pacific Ocean, making them the first people to reach the deepest point on Earth. Now, more than 50 years later, it looks like two new attempts will be made, including one in this frightening looking three man submarine from Triton.
When Don Walsh and Jacques Piccard made their groundbreaking trip in January 1960, a grand total of six people had climbed to the summit of Mount Everest. Now 51 years later, over 3000 people including a 13 year old boy have climbed world's tallest peak, while nobody else has gone the other way to reach the bottom of the ocean. So clearly this is a much more exclusive challenge.
The Triton 36,000 submarine is built with a thick glass sphere that opens up like a clamshell for access. Triton says that the dome actually gains strength as the water pressure increases. That sounds great on paper, but with about 15,750-psi of pressure at the bottom of the world, I'm not sure I would want to be the one testing that theory. That kind of pressure will crush a human like an 18 wheeler rolling over a soda can.
Let's just hope they don't crash into Richard Branson on the way down.
