Who is responsible for shrinking of Titanic

Captain Smith

Smith failed the passengers and crew of Titanic. He failed to heed ice warnings, did not slow his ship when ice was reported directly in his path and allowed lifeboats to leave the sinking ship partially filled, unnecessarily adding at least 500 names to the list of the dead. 

Shrinking date : 13 May 1911.

Shrink in Atlantic Ocean.
