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.
Wreck of the RMS Titanic
In 1995, Canadian director James Cameron chartered the "Akademik Mstislav Keldysh" and the "MIRs" to make 12 dives to "Titanic". He used the footage in his blockbuster 1997 film "Titanic". The discovery of the wreck and a "National Geographic" documentary of Ballard's 1986 expedition had inspired him to write a synopsis in 1987 of what eventually became the film: "Do story with bookends of present day scene of wreck using submersibles intercut with memories of a survivor and re-created scenes of the night of the sinking. A crucible of human values under stress." Cameron's expedition did not salvage anything from the ship.
