It seems the world hasn't learned anything after the recent Titanic submarine disaster and the sinking of the main Titanic ship itself. Now, a new cruise ship called Icon of the Seas is all set to launch, and it claims to be the ‘world’s largest cruise ship’. The RMS Titanic was at a time the largest ship in the world. The Royal Caribbean International, people behind creating Icon of the Seas, has now staked a claim to their "first-of-its-kind" ship being five times larger than the ill-fated Titanic.
