<p class="MsoNormal" style="margin:0in 0in 10pt;line-height:115%;font-size:11pt;font-family:Calibri,"sans-serif"">After more than a century of use as a maritime distress
signal, “SOS†has become shorthand for just about any emergency. You may have heard
that it stands for “save our ship†or “save our souls,†but that’s actually a
backronym, or an acronym made up after the fact. The letters in “SOS†didn’t
initially stand for anything; they were originally chosen because they form a
sequence of Morse code that can be transmitted more quickly than others.</p>
<p class="MsoNormal" style="margin:0in 0in 10pt;line-height:115%;font-size:11pt;font-family:Calibri,"sans-serif"">Morse code (named for Samuel Morse) is a way of transmitting
phrases with light flashes or electrical pulses; each letter and numeral has
its own sequence of between one and five short bursts (known as “dots†or
“ditsâ€) and long bursts (“dashes†or “dahsâ€). In 1901, inventor Guglielmo
Marconi created a radio transmitter that could send Morse code signals across
the Atlantic, allowing ships to communicate with other vessels and land-based
stations. British operators were already using “CQ,†or “seeking you,†as a
signal to alert all stations, so Marconi’s wireless company recommended “CQD,â€
or “seeking you, distress,†as an emergency signal. Meanwhile, the United
States usually used “NC,†the Germans used “SOE,†and Italians used “SSSDDD.â€
But the problem with all of these is they required brief pauses between the
letters.</p>
<p class="MsoNormal" style="margin:0in 0in 10pt;line-height:115%;font-size:11pt;font-family:Calibri,"sans-serif"">Delegates at the 1906 International Radiotelegraph
Conference suggested a simpler, more standardized distress call. The letters
“S†and “O†— three dots and three dashes, respectively — are extremely simple
and easy to understand without any spaces, so “SOS†could be transmitted on a
quick, continuous loop. Most countries officially adopted the code in 1908 and,
even though the U.S. was not among them, an American ship was the first to use
the signal when its propeller snapped. “CQD†remained popular with the British
even after other countries had adopted “SOS,†and when the RMS Titanic sank in
1912, it signaled for help with both “SOS†and “CQD.†By that time, the
backronym had already taken hold. During the British government inquiry on the
Titanic disaster, Attorney General Rufus Isaacs was under the impression that
“SOS†stood for “save our souls.â€</p>
<p class="MsoNormal" style="margin:0in 0in 10pt;line-height:115%;font-size:11pt;font-family:Calibri,"sans-serif"">The year the U.S. phased out Morse code for maritime
communications -- 1999</p>
<p class="MsoNormal" style="margin:0in 0in 10pt;line-height:115%;font-size:11pt;font-family:Calibri,"sans-serif"">Also, did you know? The
distress signal “mayday†comes from a French word.</p>
<p class="MsoNormal" style="margin:0in 0in 10pt;line-height:115%;font-size:11pt;font-family:Calibri,"sans-serif"">In the 1920s, there was a lot of air traffic between England
and France, and radio communication between pilots was spoken, not telegraphed.
While “SOS†is very practical to transmit using Morse code, it can be easily
garbled when said out loud — an “S†can sound like an “F†or even an “X.†The
term “mayday,†coined in 1923, is a phonetic spelling of the French m'aidez,
meaning “help me,†and was preferred for spoken communication. Although the
observance of the May Day spring festival predates the “mayday†code by
hundreds of years, it’s unrelated to the distress call.</p><p class="MsoNormal" style="margin:0in 0in 10pt;line-height:115%;font-size:11pt;font-family:Calibri,"sans-serif"">===============</p><div><br></div></div>
