RMS Titanic
RMS Titanic was a passenger liner that sank super Britain in the North Atlantic Ocean on April 15, 1912 after hitting an iceberg on its maiden voyage from Southampton, England to New York City. The sinking of the Titanic resulted in the death of as many as 1514 people in one of the disasters of the deadliest peacetime maritime history. Titanic was the largest ship in the world on its maiden voyage. One of the three Olympic-class ocean liner operated by the White Star Line. The ship was built in 1909 to 1911 by Harland and Wolff shipyard in Belfast. The ship is capable of carrying 2224 passengers.
The passengers consisted of a number of the richest people in the world, and more than a thousand emigrants from the United Kingdom, Ireland, Scandinavia, and other countries who are looking for a new life in North America. The ship was designed as comfortable and as luxurious as possible, with well equipped gymnasium, swimming pool, library, upscale restaurants and luxury cabins. This ship also has a cutting-edge wireless telegraph operated for the purpose of passenger and vessel operations. Although Titanic has advanced safety equipment such as watertight compartments and watertight doors that can be operated from a distance, the ship did not have enough lifeboats to accommodate all passengers. Due to safety regulations ancient sea, the Titanic had only a lifeboat that can only accommodate 1178 passengers - one-third of the total passengers and crew.
After leaving Southampton on 10 April 1912, the Titanic stopped at Cherbourg, France and Queenstown (now Cobh), Ireland before sailing west to New York. On 14 April 1912, four days after shipping, exactly 375 miles south of Newfoundland, the ship hit an iceberg at 23:40 (ship time; UTC-3). This resulted in a collision rather swipe Titanic hull plate inward in some places on the starboard side and ripped five of sixteen water-tight compartments. For two and a half hours later, the boat slowly filled with water and sank. The number of passengers and crew were evacuated into lifeboats, most have been released in a state of half-full. Many men in disproportionate numbers - nearly 90% in Year Two - abandoned because officers were loading the lifeboats comply with the protocol "women and children first". Just before 2:20 pm, Titanic broke and bow down with a thousand people on board. The people in the water died within minutes due to hypothermia because of contact with a very cold ocean. 710 passengers safely removed from the boat by the RMS Carpathia a few hours later.
The calamity was received with shock and outrage over the number of casualties and the failure of regulation and operation happens. Public inquiry in Britain and the United States pushing a major overhaul marine safety. One of the most important legacy of this disaster was the establishment of the International Convention for the Safety of Passengers at Sea (SOLAS), which still governs marine safety until now. Many survivors lost all their wealth and possessions and being poor, many families, especially families of the crew of Southampton, loses its main source of income. They all helped by a flood of sympathy and charitable donations from the community. Some of the men who survived, especially the head of the White Star Line, J. Bruce Ismay, denounced as a coward for abandoning ship when passengers are still on it, and they were ostracized by the public.
Wreck of Titanic still on the sea floor, slowly crushed in the depths of 12,415 feet (3.784 m). Since it was rediscovered in 1985, thousands of artifacts taken from the seabed and exhibited in various museums around the world. Titanic has become one of the famous ship in history. Its existence continues to be remembered by a number of books, films, exhibitions, and memorials.
