Pacific Ocean

Lost into the Pacific Ocean while on a flight from Baker Island to Makin Atoll, in the Gilbert Islands. No trace of the aircraft nor the crew was ever found.

Disappeared en route from North Island-Halsey Field NAS (San Diego) to Kaneohe Bay NAS, Hawaii. No trace of the aircraft nor the crew was ever found.

En route from Hickam AFB (Honolulu) to Cooper Airfield on Palmyra Atoll, the aircraft disappeared into the ocean while approaching Palmyra. As the aircraft did not arrive, SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the 14 crew members was found. The last radio contact with the crew reported a position about 80 km northeast of Palmyra Atoll.

The aircraft left Pocatello Airport at 0551LT on a training mission with 10 crew members on board. The program consisted on an overflight of Klamath Falls, Oregon, Fort Dick, California, then over the Pacific Ocean and eventually Hamilton Field before returning to Pocatello with an arrival scheduled in the evening. The crew contacted ground around 0820LT to confirm they overflew Klamath Falls about one hour earlier and this was the unique radio contact. Nothing further was heard from the aircraft or its crew. As the aircraft did not return to its base, SAR operations were conducted but eventually suspended after few days as no trace of the aircraft nor the crew was found. It is believed that the aircraft may have crashed into the Pacific Ocean, along the Oregon or California coast, but no trace was ever found.

All three crew members were rescued while the aircraft sank and was lost.

Lost without trace in the Pacific Ocean while performing a flight from Dillingham (Oahu Island, Hawaii) to North Island-Halsey Field NAS, San Diego.

The accident occurred when the seaplane went out of control as the pilot was trying to avoid a collision with a small boat. The aircraft sunk and was lost. Three crew members were killed while two others were rescued.

En route, the crew encountered poor weather conditions. In stormy weather, the seaplane went out of control and crashed into the Pacific Ocean. No trace was found.
