David Blair, from Broughty Ferry, was originally appointed the Second Officer of the RMS Titanic. He had been with the ship during its trial voyages to test the ship's seaworthiness and the final journey from its place of construction in Belfast. The White Star Line, however, decided that with the Titanic's sister ship, the RMS Olympic, currently undergoing layovers, to have the Olympic's Chief Officer, Henry Wilde take the position, citing his experience with ships of the Titanic's class as a reason. Chief Officer William Murdoch and First Officer Charles Lightoller were thus demoted one-step in rank, removing Blair from the command roster. Blair wrote about the disappointment of losing his position on the Titanic in a postcard to his sister-in-law days before the Titanic left for Southam
