 | | ROBERT BALLARD: Well, there actually were five ships from the Roman period, eight in all, through the entire discovery effort. |
 | | ROBERT BALLARD: Well, in fact, with the Titanic, when we found it and then went on to find the Bismarck, Titanic was in 12,000 feet of water. |
 | | ROBERT BALLARD: Well, the NR-1, which is based right nearby in my hometown in Groton, New London, has an incredible sonar system on its bowel, and it can reach out 10 times further than the sonars I was using when I was finding the Titanic and the Bismarck and ships in Guadalcanal. |
