Formal definition:-
"Angles and Dangles" is a submariners' term for a critical exercise that usually takes place right after a
nuclear submarine leaves on a patrol. Once in deep water, the sub dives deep and then comes back up,
both at a steep angle. Anything that is not properly secured will fall down, making some noise. These are
known as dangles, and they must be corrected before a sub is fully rigged for silent running. Basically, you dive
deep, come up steep, and listen to the result.''
