Donald Walsh and Jacques Piccard became the first humans to reach the bottom of the Mariana Trench, the lowest point of the world’s oceans, on January 23, 1960. They reached a depth of 35,797 feet below sea level.

On March 26, 2012, James Cameron repeated the journey in a 1-man craft. (Mr. Cameron is better known for making movies about blue people.)
Cameron’s vessel, called “Deepsea Challenger” made the voyage to the bottom of the sea without incident. However Deepsea Challenger did not survive a later journey on Interstate 95, catching fire while on the back of a truck—resulting in a total loss. Curiously, the unexpected destruction of an extraordinarily expensive seagoing vessel was the subject of one of Mr. Cameron’s motion picture shows, named “Titanic.” The similarity ends there, as the Titanic was destroyed in the north Atlantic, not on I-95 in Connecticut.
