Nichol Paul Sias, a 58-year-old pilot, disappeared on August 11, 1996, when his white Grumman Turbine G-21A Goose aircraft departed Anderson Bay in Alaska for a 20-minute flight to Dutch Harbor with co-pilot William Cork. Part of the plane was discovered on a beach in Constantine Bay, approximately 6 miles northeast of Unalaska, suggesting a crash, but the full circumstances and final fate of both men remain unknown.
