Forty-two years ago today, on December 26, 1983 (November 23, 1983 lunar calendar), French divers set a new diving record of 4,500 meters deep. On December 26, 1983, French divers set a diving record by diving to a depth of 4,500 meters hundreds of kilometers away from the sea. The four French-Arab explorers, led by a journalist Frances Le Guay, dived deep into the Cockerbidi Cave in the desert of southwestern Australia. The dive was a 39-hour challenge to the cold and stillness, a record that Osier wished would be broken in 1984.
