RMS Titanic

The RMS Titanic was an Olympic-class passenger liner owned by the White Star Line and built at the Harland and Wolff shipyard in Belfast, United Kingdom. For her time, she was the largest passenger steamship in the world.
On the night of 14 April 1912, during her maiden voyage, Titanic hit an iceberg and sank two hours and forty minutes later, early on 15 April 1912. The sinking resulted in the deaths of 1,517 people, making it one of the most deadly peacetime maritime disasters in history. The high casualty rate was due in part to the fact that, although complying with the regulations of the time, the ship did not carry enough lifeboats for everyone aboard. The ship had a total lifeboat capacity of 1,178 persons even though her maximum capacity was 3,547 people. A disproportionate number of men died also, due to the women-and-children-first protocol that was followed.
The Titanic used some of the most advanced technology available at the time and was, after the sinking, popularly believed to have been described as “unsinkable”.[4] It was a great shock to many that, despite the extensive safety features and experienced crew, the Titanic sank. The frenzy on the part of the media about Titanic's famous victims, the legends about the sinking, the resulting changes to maritime law, and the discovery of the wreck have contributed to the interest in and fame of the Titanic that continues to this day.
One of the most widely spread legends linked directly into the sectarianism of the city of Belfast, where the ship was built. It was suggested that the ship was given the number 390904 which, when read backwards as reflected by the water's surface, was claimed to spell 'no pope', a sectarian slogan attacking Roman Catholics that was (and is) widely used provocatively by extreme Protestants in Northern Ireland, where the ship was built. In the extreme sectarianism of north-east Ireland (Northern Ireland itself did not exist until 1920), the ship's sinking, though mourned, was alleged to be on account of the sectarian anti-Catholicism of her manufacturers, the Harland and Wolff company, which had an almost exclusively Protestant workforce and an alleged record of hostility towards Catholics. (Harland and Wolff did have a record of hiring few Catholics; whether that was through policy or because the company's shipyard in Belfast's bay was located in almost exclusively Protestant East Belfast — through which few Catholics would dare to travel — or a mixture of both, is a matter of dispute.)[79]
The 'no pope' story is in fact an urban legend, with no basis in fact. RMS Olympic and Titanic were assigned the yard numbers 400 and 401[80] respectively. The source of the story may have been from reports by dockworkers in Queenstown (Cobh) of anti-Catholic graffiti that they found on Titanic's coalbunkers when they were loading coal.
