In 1965, Cousteau was an Oceanaut on the
Conshelf III, an undersea habitat for saturated diving down to 325 feet near Ile Levant in the Mediterranean Sea. In addition to his duties as Oceanaut, Cousteau was an underwater photographer and did all of the underwater filming, which became a National Geographic documentary film that aired in 1966. Cousteau appeared as himself on the 28 March 1966 episode of the CBS game show
To Tell the Truth. He received three of the four possible votes from the panel. In February 1967, Cousteau accompanied his father on the
RV Calypso for an expedition to film the
sharks of the
Red Sea and the
Indian Ocean. As well as being the lead photographer for the expedition, Cousteau also chronicled his experiences in the 1970 publication
The Shark: Splendid Savage of the Sea. In 1969, Cousteau lent his technical expertise to the
U.S. Navy's
SEALAB program. In the aftermath of
aquanaut Berry L. Cannon's death while attempting to repair a leak in SEALAB III, Cousteau volunteered to dive down to SEALAB and help return it to the surface, although SEALAB was ultimately salvaged in a less hazardous way. Until his death in 1979, he co-produced numerous documentaries (1977), concerning environmental issues. ==Piloting==
