Was reading about undersea com/internet cables. Then just started thinking about how wild it would have been if a wreck like the Titanic had been messed up even more if a cable (or cables) had been dropped on it (or even found due to laying them).

I started searching, but there are too many articles about the cables being damaged and/or sabotaged. But aside from some that talk about potential impact of the environments where they are laid, I haven't seen anything about damaging shipwrecks by the cables or discovering any while being placed.

Would imagine that most of the cables are placed outside of really busy shipping routes, and avoid unnecessarily deep sections. Still would be kind of interesting to know.
