Olympic-class ocean liner
When "Titanic" sank in 1912 and "Britannic" sank in 1916, their sinkings did not receive the same attention, due to the death toll (1,517 on "Titanic" and 30 on "Britannic"). Because the exact position of the sinking of the "Britannic" is known and the location is shallow, the wreck was discovered relatively easily in 1975. "Titanic", however, drew everyone's attention in 1912. After several attempts, the wreck was finally located by Jean-Louis Michel of Ifremer and Robert Ballard following a top secret mission for the US Navy to investigate the wreckage of two nuclear submarines, USS Thresher (SSN-593) and the USS Scorpion (SSN-589), that sank in the North Atlantic in the 1960s. The discovery of the wreck occurred on 1 September 1985, at 25 kilometres from the position given of the sinking. The wreck lies about 4,000 metres deep, broken in two. The bow is relatively well preserved, but the stern partially imploded, and to a large extent disintegrated during the descent and impact on the seabed.
Timeline of United States discoveries
The RMS "Titanic" was an "Olympic" class passenger liner owned by the White Star Line and was built at the Harland and Wolff shipyard in Belfast, in what is now Northern Ireland. At the time of her construction, she was the largest passenger steamship in the world. Shortly before midnight on April 14, 1912, four days into the ship's maiden voyage, "Titanic" struck an iceberg and sank two hours and forty minutes later, early on April 15, 1912. The sinking resulted in the deaths of 1,517 of the 2,223 people on board, making it one of the deadliest peacetime maritime disasters in history. After nearly 74 years of being lost at sea on the bottom of the ocean floor, a joint Franco-American expedition led by American oceanographer Dr. Robert D. Ballard, discovered the wreckage of the RMS "Titanic" two miles (3 km) beneath the waves of the North Atlantic on September 1, 1985. Ballard was then forced to wait a year for weather conditions favorable to a manned mission to view the wreck at close range. In 1986, Ballard and his two-man crew, in the ALVIN submersible, made the first two and-a-half hour descent to the ocean floor to view the wreck first-hand. Over the next few days, they descended again and again and, using the Jason Jr. remote camera, recorded the first scenes of the ruined interior of the luxury liner.
