Consolidated PBY Catalina

Enroute from Belém to Manaus, the seaplane crashed in unknown circumstances in the region of Porto de Moz. As the aircraft failed to arrive in Manaus, SAR operations were conducted but eventually suspended few days later as no trace of the aircraft was found. On December 22, 1947, the wreckage and the dead bodies of all 16 occupants were found near the village of Aquiqui, northwest of Porto de Moz.

The aircraft was on its way from Kodiak to Unalaska, carrying a crew of five and fifteen members of a Navy football team. While cruising some 250 km from the destination, the crew informed ground he encountered strong head winds. Shortly later, the seaplane crashed in unknown circumstances into the sea. All 20 occupants were killed.

While landing in the Svolvær Bay, the seaplane went out of control and plunged into the water before coming to rest. There were no casualties among the 12 occupants while the aircraft was damaged beyond repair.

The crew left Port Angeles in the morning on a flight to Elizabeth City, North Carolina, with a first intermediate stop scheduled in Medford, Oregon. The purpose of the flight was to convoy the seaplane for maintenance in Elizabeth City. After four hours into the flight, the crew encountered poor weather conditions. While flying at a height of some 5,000 feet, the left wing hit a peak and was sheared off. The aircraft crashed and burst into flames on the slope of Mt Richter, at the altitude of 4,200 feet. Both passengers were rescued while four crew members were killed.
