This episode involves the testing of a new air mixture that will allow a submarine to go to the "bottom of the sea" literally! A brash, news hogging, admiral and his aide, along with his assistant all successfully make the first tests in a diving bell. Then it is time for the Seaview to follow suit. Only then does the real fun begin! Written by
