Tissue-thin

The extreme skinniness of the shadow of the rings against Saturn's cloud top settles once and for all the extreme silliness of film depictions of spaceships flying through huge debris fields when passing through planetary rings. You can't even see it in the thumbnail, so thin the region is, so the pilot and navigator would have to be aiming for that razor's edge to be in the right place for it to be a problem.

Plus I'm pretty sure the contents of these ring systems is much smaller than the huge boulders the CGI team likes to toss around.
