While cruising at an altitude of 14,000 feet, the right engine failed and the fuel pressure decreased. The crew attempted to restart the right engine without success and pilots were unable to feather the propeller. Due to high drag, the aircraft lost height and at an altitude of 8,000 feet, all occupants decided to bail out as the minimum safe altitude for the region was set at 9,000 feet. Out of control, the aircraft dove into the ground and crashed in a valley near Lovelock. Fourteen occupants were found alive while one crew member (Pfc George E. Johnson) was killed as his parachute did not open properly.

Following an uneventful mission, the crew was returning to Casco Cove Guard Station on Attu Island. On approach, the pilot realized that the sea was rough and decided to continue to the Massacre Bay where the situation seemed to be easier. On landing, the seaplane was hit by a wave and plunged into the sea. While all occupants were able to evacuate the cabin, the aircraft sank and was lost. It was carrying a cargo of 1,200 gallons of fuel and two bombs.

The crew was completing a routine training flight and left Fort Benning AFB in the early morning. While cruising at an altitude of 5,000 feet, a technical failure occurred on the left engine from which all propeller blades broke away. The engine suffered severe vibrations and detached few seconds later, causing the wing to be partially torn off. Out of control, the aircraft dove into the ground and crashed, killing all four occupants.
Crew:
Cpl Vincent James Faggione,
2nd Lt Orville Clarence Hern,
2nd Lt Melvin Lloyd Jenkinson,

The crew was engaged in a test flight when the seaplane crashed in unknown circumstances off Miami. A crewmen was killed.

During a night training mission, the seaplane was landing on the Perquimans River when it nosed down and sank. All six crew members were killed.

In the evening, the crew left McClellan AFB, near Sacramento, on a routine flight to Seattle, Washington. After take off, the pilot completed a circuit over the airport to reach the assigned altitude of 16,500 feet and reduced the engine power to 2,300 RPM. After few minutes, the right engine failed, followed shortly later by the left engine. A crew member was able to bail out before the aircraft went out of control, dove into the ground and crashed in a huge explosion. All five occupants were killed while the sixth was found alive.
