Then why Gibson saw three signals in 3 minutes interval? In any case as me you do not accept Sam’s explanation that Californian was swinging back and forth without anybody noticing?In fact it is quite possible that Californian was yawing in the northerly wind that had set up after 3 am. However she would not have been see-sawing but changing her heading over a considerable number of minutes. Carpathia was firing a distress signal followed immediately by a Company signal at 15 minute intervals. Work it out for yourself.
