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.
Titanic (1997 film)
Principal photography for "Titanic" began in July 1996 at Dartmouth, Nova Scotia, with the filming of the modern day expedition scenes aboard the "Akademik Mstislav Keldysh". In September 1996, the production moved to the newly built Fox Baja Studios in Rosarito, Mexico, where a full scale RMS "Titanic" had been constructed. The poop deck was built on a hinge which could rise from zero to 90 degrees in a few seconds, just as the ship's stern rose during the sinking. For the safety of the stuntmen, many props were made of foam rubber. By November 15, the boarding scenes were being shot. Cameron chose to build his RMS "Titanic" on the starboard side as a study of weather data revealed it was a prevailing north-to-south wind which blew the funnel smoke aft. This posed a problem for shooting the ship's departure from Southampton, as it was docked on its port side. Implementation of written directions, as well as props and costumes, had to be reversed; for example, if someone walked to their right in the script, they had to walk left during shooting. In post-production, the film was flipped to the correct direction.
