It does at first seem like a no brainer, but when you think of it if the people doing it are jumping into deep water from a reasonable height and are good divers / swimmers then they could do it. But I would not dream of ever doing it myself.
I worry that young people who do not know what they are doing might try it and get it badly wrong, as the lifeboat man (Ray Barton) said "get it wrong and you end up with a tombstone".
I have to admire the men of the RNLI, they are not paid and they are brave and skilled men who are in the same class as the pararescue man Jack Brehm. I have read his book "That others might live" and he was some very good things to say about what a hero is. Jack commented that a "normal" firefighter who enters a burning house to rescue a goldfish is more than a hero than a sports star who does well at his sport.
