Here CruiseMapper offers two top-rated YouTube videos about RMS Titanic's sinking.
The first video suggests the ocean liner was actually switched with the damaged sister-vessel RMS Olympic. The evidences are too many and too much.
The second video is about the undisputed fact that during RMS Titanic's maiden (first and last) voyage from Southampton England, the ship left port on a Transatlantic crossing to NYC New York with an ongoing fire onboard.
