Unrelated to the contents on the article but the wording of the title made me think that the Harvard Professor crashed into the Pacific Ocean. You might want to consider clearing it up.
To be fair, if a Harvard professor impacted the ocean that hard and on that trajectory, that would also be news.
I don't think a Harvard professor could be retrieved from the ocean floor using a magnet. Unless he had been an android, in which case I guess that would be worth investigating.
