The Stacks
The Titanic had four large stacks on top of the ship. This was to help ventilate the smoke from the furnaces through these funnels. When the water began to get into the ship, the firemen panicked about the reaction of the ice-cold water and the boiling hot furnaces. An explosion was avoided because they acted quickly to vent as much steam as possible from these stacks.
Surviving Stewards
Out of the 908 crew members on board, 421 of them were stewards (waiters and maids). Only 60 stewards survived, and 48 of them were women. The photo above shows steward Thomas Whitely. His leg was crushed when a piece of debris fell on him as he boarded a lifeboat.
