And Cameron has made it!

Filmmaker reaches new depths

And James Cameron is at the bottom of the Mariana Trench, looking for a pre-dropped probe which included exposed bait for undersea creatures.  The only people who have ever  been at this depth reported a living flatfish, although many authorities consider it a misidentified holothurian (sea cucumber).  Cameron, equipped with a manipulator arm and a "slurp gun," might bring up some entirely new species.

COMMENT: Congratulations, Mr. Cameron!  Now I hope you'll take the next step: broadening this feat into a durable program of exploration and discovery.
