Christopher Mark Loennig was 26 when he went missing from a work vessel in Dutch Harbor, Alaska, on November 16, 1986. He was wearing rain gear and rain boots while retrieving buoy bags when he was struck and knocked overboard into calm but frigid waters. Rescue teams responded immediately, but neither Christopher nor his body was recovered.

The incident was officially classified as a suspected accident. A friend later recalled Christopher saying he felt more afraid during calm moments at sea than in storms and described the circumstances as somewhat suspect, but the official account remains that he was accidentally knocked from the vessel while working.
