The first person to reach the bottom of the Marianas trench was French explorer and scientist Piccard, in the bathyscaph. This was a type of submarine that was filled with a liquid (gasoline, I believe) as ballast, to be able to resist the incredible water pressure. The part where the people went was a sphere suspended beneath the hull of the ballast tank. In essence, the vehicle was like a hot-air ballon but for going underwater. This immersion happened in 1957.

∙ 13y agoThe first sub to reach the floor of the Mariana Trench was a manned sub called "Trieste". The Trieste broke a record at diving 10,900 feet! It took 5 hours just to reach the floor! 5,000 new species of animals were discovered during this expedition, thus making the Global Animal Species List (GASL) longer!
