The problem is that the word "fall" does decribe the action of descending through the air, but it also implies a lacjk of personal responsibility for what happned.
Subsequent reports say she very likely "jumped" before she "fell" so those of us who really care about accuracy find a world of difference between the two words.
I prefer that news reports use the term "went overboard" - even though it is also a vague term at least it doesn't imply there was something faulty about the ship.
I am the editor, but I also speculate, ask questions and play devil's advocate. I reserve the right to change my mind.
