There were no cameras on the sea floor and any pictures taken by Titan’s occupants were destroyed along with it, but there is film that contains what we now know to be audio of the craft’s last moment. Rush’s wife, Wendy, is aboard the mission’s support ship, in radio contact, when she hears a noise.At that point, Wendy Rush looks more confused than alarmed.
