Hedley Mattingly (Doctor on the Lusitania) was born on May 7, 1915, the same day that the RMS Lusitania was sunk by the German U-boat U-20.
In "The Lone Survivor" episode, The Survivor (John Colicos) refers to himself as a Flying Dutchman made of flesh and bone. A Flying Dutchman is a legendary ghost ship that can never make port and is doomed to sail the oceans forever.
After No Time Like the Past (1963), "Lone Survivor" was the second story written by Rod Serling to involve the sinking of the RMS Lusitania.
Although the captain of the RMS Lusitania is not given a name, the ship's commanding officer at the time of its sinking was William Thomas Turner.
The survivor gives a detailed account of the sinking of the Titanic in which he describes the ship sinking by the bow. Although this account matches the manner in which the Titanic was believed to have sank when this episode was first broadcast in 1971, it is now known that the Titanic split in half and sank in two separate pieces.
