1353:), left San Francisco for Hawaii with 38 passengers and six crew. The 377 crashed around 5:25 p.m. in the Pacific Ocean. There were no survivors and the entire wreckage has never been found. Only 19 bodies and bits of debris were recovered. There is speculation that two passengers had a motive to bring the plane down. Eugene Crosthwaite, a 46-year-old purser, had shown blasting powder to a relative days prior to the flight, and had cut a stepdaughter from his will only one hour before the flight. Pan Am concluded that there was sufficient evidence that Crosthwaite was the culprit. William Payne, an ex-Navy demolitions expert, had taken out large insurance policies on himself just before the flight, and had a $ 10,000 debt he was desperate to pay off. The insurance investigator later suspected him of never being on the plane. His wife received at least $ 125,000 in payouts. It was the opinion of the flight engineer during the 1430: 747: 1065: 377: 237: 934: 924: 914: 1379:) was on a flight from San Francisco to Singapore via several intermediate stops. As the aircraft touched down at Manila (runway 06) in a heavy landing in rainy and gusty conditions, the undercarriage collapsed as a result of the hard landing. The plane skidded and swerved to the right, coming to rest 2,850 feet past the runway threshold and 27 feet from the edge of the runway. One of the passengers was killed when one of the blades of the number 3 propeller broke off, penetrating the passenger cabin. 362: 971: 42: 804: 1309: 1112: 796: 530:. The last flight of the 377 with United was in 1954, the last with BOAC was in 1959, and the last with Northwest was in September 1960. In November 1960, only a weekly Pan Am Honolulu to Singapore flight remained, and the 377 was retired by Pan Am in 1961. High operating costs (notably the fuel consumption and maintenance of the Wasp Major engines) led to rapid abandonment of the 377 with the onset of the jet era.

Typical airline cruise was less than 300 mph (260 kn; 480 km/h); in August 1953, Pan Am and United 377s (and United DC-6s) were scheduled between Honolulu and San Francisco (2,398 mi (3,859 km)) in 9 h 45 min each way.

The aircraft, with No. 4 propeller feathered, stalled and abruptly dived from an altitude of approximately 300 feet and was destroyed upon impact in San Francisco Bay. All three crew aboard were killed. The probable cause was an inadvertent stall at low altitude. 1151:, and failures related to engine cooling. Six propeller failures between 1950 and 1955 resulted in separation or near-separation of engines from mounts, with two resulting in hull-loss accidents. Directives were issued in 1950, 1955, and 1958 regarding enhanced maintenance and fault detection, in-flight vibration monitoring, and propeller replacement. 287:
compared to 125 inches for the DC-6 and other Douglas types (and 148 inches for today's 737). The lower deck served as a lounge, seating 14. The 377 had innovations such as higher cabin pressure and air conditioning; the superchargers on the four Pratt & Whitney R-4360 engines increased power at altitude and allowed constant cabin pressure.

Within six years of first delivery, the Stratocruiser had carried 3,199,219 passengers; it had completed 3,597 transcontinental flights, and 27,678 transatlantic crossings, and went between the United States and South America 822 times. In these first six years, the Stratocruiser fleet had flown 169,859,579 miles (273,362,494 km). 427:. In 1954, United Stratocruisers flew Los Angeles to Honolulu and between Seattle and San Francisco; United's B377 flights to Honolulu were all first class. In 1955, BOAC 377s had 50 First Class seats (fare $ 400 one way New York to London) or 81 Tourist seats (fare $ 290). In 1956, Pan Am 377s flew from Los Angeles and San Francisco to 1274:

This aircraft type suffered 13 hull-loss accidents between 1951 and 1970 with a total of 139 fatalities. The worst single accident occurred on April 29, 1952. The aircraft type also experienced a significantly high rate of in-flight emergencies related to engine and propeller failure, resulting in

The longest (by distance) 377 nonstop flights were made by Pan Am from Tokyo to Honolulu during four winter seasons beginning in 1952–1953. In January 1953, two nonstops a week were scheduled with a flight time of 11 hr 1 min due to tailwinds; the following August all flights took 19 hours, with a

The 377 shared the distinctive design of the C-97, with a "double-bubble" fuselage cross-section, resembling a figure-8, with the smaller loop on the bottom, with 6,600 cubic feet (190 m) of interior space shared between two passenger decks. Outside diameter of the upper lobe was 132 inches,

The exception was Northwest Airlines, who managed to keep the aircraft competitive on shorter U.S. domestic routes where the aircraft's higher payload capacity benefited from lower fuel weights. United however could not integrate their six-plane fleet of 377s. By 1954, the lack of spares and the
