Rob Thomas Mourant was 23 when he boarded a flight from Port Walter to Port Lucy on July 18, 1981. Also on board were Judy Riddell, Randall Riddell, and Norman Riddell, who piloted the aircraft. The plane was reported overdue and, despite an intensive search, no wreckage or bodies were ever found.

Mourant was a recent business administration graduate and a prominent student leader: he served as the first student body president at both the University of Alaska Anchorage and the University of Alaska Southeast and helped found the statewide Alaska Student Lobby. Fellow students campaigned to name the student center under construction in his honor; the University of Alaska Board of Regents approved the proposal and the Mourant Building at the University of Alaska Southeast bears his name.

The four aboard are presumed dead and the aircraft is believed lost off the west side of Chichagof Island. The rugged terrain and severe weather in the area are noted factors, and the absence of any wreckage or remains has left questions unanswered for family and community.

If anyone knew Rob, the Riddells, or was in that area in July 1981, can you share information that might help clarify what happened?
