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 with his father, including Voyage to the Edge of the World (1976) for the cinema and his own PBS television series, Oasis in Space (1977), concerning environmental issues. Piloting Cousteau was a highly experienced pilot. He earned his glider pilot license at the age of 16 and went on to obtain pilot credentials to fly balloons, hang gliders, single- and multi-engine airplanes and seaplanes, gyrocopters and helicopters. He acquired a PBY Catalina seaplane in 1974. The amphibious aircraft was a converted U.S. Navy Catalina flying boat. Christened the Flying Calypso, the aircraft was in many of the Cousteau films and the home base for Cousteau's team. Personal life Cousteau met Janice Sullivan in the crowded ballroom of St. Regis Hotel in New York City in February 1966. She was a fashion model originally from Los Angeles and more recently from New York. On 10 February 1967, they were married in Paris. Sullivan joined Cousteau on most of his father's expeditions (20 of 26 filming expeditions that spanned 13 years). They had two children, Alexandra Cousteau and Philippe Cousteau Jr. Death and legacy Cousteau died in 1979, aged 38, when his PBY Catalina flying boat crashed in the Tagus river near Lisbon. The investigation of the accident was not thorough, and competing theories exist to the present day. One theory is that the aircraft simply touched down on the river too fast, causing it to flip on the water; another is that the aircraft nosed over during a high-speed taxi run undertaken to check the hull for leakage and the left wing broke free, sending its engine toward the cockpit and killing Cousteau instantly. Still another theory is that the aircraft, an amphibian with fully retractable landing gear, landed on the river with the landing gear extended. All others on board survived. His son Philippe Cousteau Jr. was born six months later. The Philippe Cousteau Anchor Museum in Asturias, Spain, and The Lycée Philippe Cousteau in Saint-André-de-Cubzac, France, honor Cousteau's work. His children Alexandra Cousteau
