As a small kid I recall reading National Geo all about the Trieste descending the Marianas Trench. I followed James Cameron's expedition closely and now this new generation of deep ocean exploration. This is the first submersible designed to travel to any and every part of the sea floor, rapidly and repeatedly. It has a very bright future of discovery ahead of it, since the billionaire adventurer who bankrolled it will provide it to the world'soceanic institutes and researchers after his personal exploration project is completed. Go figger they'd find a plastic bag and candy wrapper 11 km, (7 miles) below the surface. https://www.bbc.com/news/science-environment-48230157
