The first was the warning message sent by the S.S. Mesaba to the Titanic, signalling the presence of large quantities of ice and numerous icebergs. The message was acknowledged by one of the two telegraph operators on board but overwhelmed by the volume of telegrams being sent that evening, he never passed it on to the captain. The students explained that according to Shannon's model, this cannot strictly be considered a case of noise, as the problem did not lie between sender and receiver, but between the receiver and the final destination of the message.
Several hours later, at 11:40pm, the Titanic struck the iceberg. The operator sent a distress signal CQD to the R.M.S Carpathia, located more than 300 kilometres away. The Carpathia decoded the message correctly and set course for the scene, responding in morse that it was on its way. The students noted that this is the one exchange where, according to Shannon's model, communication actually worked, and yet the Carpathia arrived one hour and ten minutes after the Titanic had completely sunk, rescuing only the 705 passengers already in lifeboats. The students also examined the light signal sent by the Titanic to the S.S. Californian, located approximately thirty kilometres away. Due to the refraction of light in the fog, the Californian interpreted the distress signals as ordinary navigation lights and sailed on. The students observed that the level of entropy, already high since the Mesaba's undelivered warning, continued to rise with each failed exchange.
For the fourth scenario, the students applied Lasswell's model to the press coverage that followed, examining how newspapers reported on the tragedy and how the wave of emotion that followed led to significant changes in maritime safety regulations, including the permanent replacement of the distress code CQD by SOS. A morse code alphabet and decoding tree were also made available to visitors, inviting them to decipher for themselves the actual messages exchanged between the ships on the night of the sinking.
