A Dutch company built a submarine that can hold 10 passengers and 1
pilot. The submarine has a safety feature that will automatically raise the
submarine if it goes below the certified depth of -650 feet. To show this
feature to a buyer the submarine dove to a depth of -872 feet. The
automatic feature then raised the submarine 50 feet per minute.
