so I'm not sure how to check on this BUT I recall when I was watching Unsolved Mysteries as a kid that the same little girl was rescued from both the Titanic and the Britanic by the SAME lady who was not there in relation to the kid either time.
What I mean by that is the lady was not the kids nanny or anything, because that would just make sense that she saved the kid both times if she had been there to accompany the child. But she was I believe working as a Nurse in the ships infirmary for Titanic and was just a passenger on the Britanic but she saved the same little girl (once a baby and once a toddler I think)
To me that was pretty crazy

The Olympics are also great for this! There is some small land locked country that the first medal they ever got from the Olympics was from a Rowing event....and they didn't even have a body of water large enough for him to practice in he had to go to another country just to train!

Kayla Harris is one of a very few people (maybe the only one?) to Win a Gold medal at two Olympics in a row! Not only win frankly she buzzsawed the other girls.

Kurt Angle won a Gold medal with a broken neck, and it was the first time the usa had ever won in that weight class

A lady who's name I forget was in her early 40's for a swim event and she had performed and medaled in it when she was younger and the announcers basically wrote her off saying it was nice of the American team to 'let her' compete or some nonsense like that and meanwhile she got a Bronze in the event and actually bettered her time from when she was in her prime!
