Jacques Piccard, co-designer of the bathyscaphe, and his assistants make final checks aboard her, prior to Trieste's first deep dive in the Marianas Trench. On 15 November 1959, off Guam, she dove to 18,600 feet, breaking the previous record of 13,000 feet. USS Wandank (ATA-204) is in the distance, apparently towing the bathyscaphe. Navigation bouy on right indicates that the photo may have been taken as Trieste left port to make the dive. Photo was released from publication on 28 November 1959.
