Yes, the Carpathia was something.
I was also impressed that sister ship, Olympic, turned around so far down the US coast to try to respond. It was too far away.
Another fascinating thing I ran across on 1 of those documentaries was about a German ship sending out messages about ice (IIRC). It apparently had run across this field and likewise as the Californian, had stopped and tried to signal.
I will say this for the CAian, as I recall (I used to be so into this but I’ve forgotten many things, so forgive errors), they tried to send out warnings. The Titanic wireless operator ignored it and even put them off as just being in the way of his telegraphs. So I have some hard feelings for the wireless guys.
The German ship was the Frankfurt. The Californian was stopped in the ice field, and was only about ten miles from the Titanic. It saw the distress flares the Titanic sent aloft, but the Californian knew the ship was the Titanic, and assumed they were just company flares. The Californian did have wireless, but not a 24-hour watch on wireless duty. Its wireless operator signed off before the Titanic sent a CQD or SOS. Interestingly, the Carpathia didn’t have a 24-hour wireless watch, either, and it was just a lucky break its wireless operator picked up the SOS before he shut down the system for the night.
