The Titanic looked like Queen Mary: 4 funnels, 2 masts, 1 propellor on the bow and starboard of the ship and one in the Well, located beneth the poop deck. The name "TITANIC" on her bow and "TITANIC, LIVERPOOL" as a strip on the Stern. Titanic was one of the first ships to look like a city on the ocean
The first person to verify to the world that Titanic sunk was Fourth-Officer Boxhall when he conferred with Captain Rostron on Carpathia.
Fourth Officer Boxhall reported to Captain Rostron on the Carpathia and confirmed the loss of Titanic.
