With Héctor Salvador, aeronautical engineer and explorer.

The deep ocean has remained unexplored for most of human history due to the great challenges people face trying to reach such a difficult environment. In this talk, the engineer Héctor Salvador, who has gone on more than 1,800 dives in 20 different submersibles and who in 2021 became the first Spaniard to go down to the Mariana Trench (at a depth of 10,706 metres) in a vehicle that was built with significant input from Catalan industry, tells the story of this manned deep-sea expedition and the adventure surrounding the design construction and operation of the first submersible certified to access any part of any ocean.
