United States Navy - USN

The crew left Subic Bay (Cubi Point NAS) bound for Naha, in formation with a reconnaissance Douglas AD-6 Skyraider registered 135350 and carrying one pilot. While approaching Naha Airport, at an altitude of 1,500 feet, both aircraft collided and crashed into the sea about 6,5 km from the airfield. All 26 occupants were killed as well as the Skyraider's pilot.

The crew was completing a flight from Argentia-Bristol Field NAS, Newfoundland, to Lajes Airbase, Azores Islands. While flying by night about 177 km west of Crovo Island, Azores, the airplane disappeared and crashed into the ocean. SAR operations were conducted for several days but no trace of the airplane nor the 22 occupants was ever found.

The aircraft departed Los Alamitos AAF for a local training flight with eight crew members on board. While cruising at an altitude of 3,000 feet, the airplane collided with a USAF Douglas C-118A Liftmaster. Registered 53-3277, it left Long Beach Airport five minutes earlier bound for McGuire AFB, New Jersey, with 35 passengers and a crew of six on board. Following the collision, both aircraft went out of control, dove into the ground and crashed in Norwalk. The Liftmaster crashed on several building and a fuel station, killing all 41 occupants and one woman on the ground. The Neptune crashed in a stone-pit located about 2.5 miles north of the C-118 crash site. Six crew members were killed while two others were seriously injured. The accident occurred by night but in good weather conditions with a visibility above 15 miles.

On a flight from Honolulu (Keehi lagoon) to Alameda NAS, the propeller detached from the engine number one and struck the fuselage, causing vibrations. The crew continued the flight to Alameda NAS and while landing on breakwater, the airplane crash landed and sank. All 21 occupants were rescued but the aircraft was lost.

After the crew completed several touch-and-go manoeuvres at Patuxent River NAS, he started a new descent in poor visibility due to foggy conditions. On final, the four engine airplane struck trees and crashed in flames short of runway threshold. The aircraft was destroyed by impact forces and a post crash fire and all nine crew members were killed. It appears the crew descended too low in marginal weather conditions.

Constellation 143197 set out on its flight two days before Christmas with a crew of 23. Commander Guy Howard Jr., executive officer of the squadron was sitting in the copilot seat, to give Commander Frederick Woodward a checkout that would qualify him as a plane commander. For five and a half hours Howard put Woodward through his paces. Then, as the Connie cruised only 1,500 feet above the ocean, Howard called for a new exercise: what would Woodward do if a fire broke out in the forward baggage compartment? Responding correctly, Woodward "cut" (disconnected by pulling circuit breakers) some electrical Circuits. But something went wrong. The plane began falling. "I thought it was a drill" Navigator Richard Rentschler later told LIFE Correspondent James Goode. "The next thing I notice was water out the starboard window." Seconds later the plane hit the water, broke in two and caught fire. As the plane hit, Rentschler was hurled under the navigator’s table and came out surrounded by flames. He pushed Radioman Franklin Henry Jr. through the escape hatch, then jumped free himself Lt Thomas Kline, pinned under the radar console, was freed by another crewman (Robert O. Clark). "I jumped through the fire," says Kline, and swam under water 50 feet to avoid the flames. Commander Howard escaped from the cockpit. Nineteen crew members were killed and four others were rescued.

Few minutes after its takeoff from Corpus Christi, the seaplane suffered an engine explosion. The airplane went out of control and crashed in flames about 18,5 miles from Corpus Christi. A crew member was seriously injured while eight other occupants were killed.

On final approach to Kodiak Airport, the airplane crashed into the sea for unknown reason, killing all nine crew members. The airplane was returning to Kodiak following a maritime patrol flight.

Crashed in unknown circumstances at or near Alameda NAS. Crew fate remains unknown.

After liftoff, while climbing to a height of 10 feet, the left engine misfired. The airplane banked left, causing the left wing to struck the ground. Upon impact, six feet of the left wing were sheared off. The pilot-in-command continued to climb, completed a downwind circuit and made an uneventful landing. There were no injuries but the aircraft was considered as damaged beyond repair.
