100 years ago in April 1912, the RMS Titanic struck an iceberg and sank during her first and last voyage. Less than a third of the passengers survived. The disaster led to new safety regulations for all sailings including the requirement that there would always be enough lifeboats to provide room for everyone on board. Thereafter, wireless telegraphs were also required to be manned at all hours to make sure a ship could be called to assistance. This image gallery covers the building of the Titanic, launch, captain and crew, the sinking, rescue and the enquiry.
