November 22, 1906: SOS
international code was adopted officially in 1908. The SOS code was
conceived by delegates who attended the Radiotelegraphic Conference in Berlin, Germany . Many people think that SOS is short for ' Save Our
Ship ' or ' Save Our Soul.' These opinions are not correct. SOS has no
special meaning, SOS was created to simplify sending morse code signals during a state
of emergency. By chance, SOS pads use the same initials because
their name is based on a patented process, Soap on Steel.
Because of the presence of radio communication technology, in 1927 International
Radio Convention stated the distress phrase "Mayday" as the equivalent of an SOS code. "Mayday" is actually the French "M'aidez" (help me).
