First distress call transmitted — CQD, later SOS

Assembled from 84 blocks · 2 evidence · 63 related

1. Story
2. Phillips began sending CQD with the position worked up by Fourth Officer Boxhall: 41°46′N, 50°14′W. That position was some 13 nautical miles from where the wreck actually lies, an error that would frustrate searchers for seventy years. SOS was used later in the same sequence. The Carpathia answered; the Californian, her set closed down, did not.

82. Evidence
83. Found the loss due to collision with an iceberg brought about by the excessive speed at which the ship was navigated; recorded the ship's particulars, the voyage timings, the ice messages received and the lifeboat complement; held that Titanic exceeded the Board of Trade requirement; found the Californian could have reached her; concluded (incorrectly) that the hull sank intact.
84. Titanic's Marconi station used call sign MGY; the operators were Marconi company employees whose principal work was passenger telegram traffic; the distress signal was sent first as CQD and subsequently as SOS.
