Has anyone gone from Aerospace Engineer to Marine Biologist?

Hi All! I have a Masters Degree in Aerospace Engineering and have worked as a flight test engineer on various programs for about ten years now. Great job, lots of fun flying backseat in fighter jets, but I also love scuba diving and ocean life and am thinking of shifting careers instead of promoting up the standard career path. Is there anyone who’s made a similar jump? Not asking advice on whether I should or should not do it (I know that’s one of the rules of posting here) , just curious about other people’s experiences and what that looked like for them. Thanks !
