The crash of Canadian Pacific Air Lines Flight 3505 occurred on 21 July 1951 when a Douglas DC-4 four-engined piston airliner registered CF-CPC of Canadian Pacific Air Lines disappeared on a scheduled flight for the United Nations from Vancouver, Canada, to Tokyo, Japan. [1] Neither the aircraft nor the 31 passengers and six crew have been found. [1] [2] The incident marked the first aircraft loss during the Korean Airlift. [3]
At 18:35 the DC-4 departed Vancouver International Airport, Canada on a scheduled flight to Tokyo; it was due to stop over at Anchorage Airport in Alaska. [2] The flight was on schedule and reported at the Cape Spencer intersection in British Columbia 90 minutes out from Anchorage; it gave an estimate of 24:00 for Yakutat in Alaska. [1] [2] The weather in the area was heavy rain and icing conditions with a visibility of 500 feet (150 m). [2] Nothing further was heard from the aircraft, and at 00:44 an emergency warning was issued when the aircraft was overdue to report. [1] The United States Air Force and Royal Canadian Air Force carried out an extensive search but failed to find any trace of the aircraft or its 37 occupants. [1] The search was finally called off on 31 October 1951. [1]
The aircraft, a Douglas DC-4 four-engined piston airliner had been built in 1944 for the United States Army Air Forces as a Douglas C-54A Skymaster but on delivery in June 1944 it was diverted to the United States Navy with the designation R5D-1. [4] In 1946, it was converted to a civil Douglas DC-4 standard for Pan American Airlines as Clipper Winged Racer. [4] It was sold to Canadian Pacific Airlines in 1950. [4]
All six crew members were Canadian. The 31 passengers included two sailors of the Royal Canadian Navy, 26 members of the United States military and 3 civilian US citizens.
None of passengers aboard the aircraft were ever found. The Douglas DC-4 was presumed destroyed beyond repair. [1]
In 1974, the Civil Aviation Authority (United Kingdom) reported: "As no traces of the aircraft or its occupants has been found to date the cause of the disappearance has not been determined." [1]
An airliner is a type of airplane for transporting passengers and air cargo. Such aircraft are most often operated by airlines. The modern and most common variant of the airliner is a long, tube shaped, and jet powered aircraft. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts.
Western Airlines was a major airline in the United States based in California, operating in the Western United States including Alaska and Hawaii, and western Canada, as well as to New York City, Boston, Washington, D.C., and Miami and to Mexico City, London and Nassau. Western had hubs at Los Angeles International Airport, Salt Lake City International Airport, and the former Stapleton International Airport in Denver. Before it merged with Delta Air Lines in 1987 it was headquartered at Los Angeles International Airport (LAX). Throughout the company's history, its slogan was "Western Airlines...The Only Way to Fly!"
Ted Stevens Anchorage International Airport is a major airport in the U.S. state of Alaska, located 5 miles (8 km) southwest of downtown Anchorage. The airport is named for Ted Stevens, who served as a senator of Alaska from 1968 to 2009. It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2017–2021, in which it is categorized as a medium-hub primary commercial service facility.
The Boeing 377 Stratocruiser was a large long-range airliner developed from the C-97 Stratofreighter military transport, itself a derivative of the B-29 Superfortress. The Stratocruiser's first flight was on July 8, 1947. Its design was advanced for its day; its relatively innovative features included two passenger decks and a pressurized cabin. It could carry up to 100 passengers on the main deck plus 14 in the lower deck lounge; typical seating was for 63 or 84 passengers or 28 berthed and five seated passengers.
The Douglas C-54 Skymaster is a four-engined transport aircraft used by the United States Army Air Forces in World War II and the Korean War. Like the Douglas C-47 Skytrain derived from the DC-3, the C-54 Skymaster was derived from a civilian airliner, the Douglas DC-4. Besides transport of cargo, the C-54 also carried presidents, prime ministers, and military staff. Dozens of variants of the C-54 were employed in a wide variety of non-combat roles such as air-sea rescue, scientific and military research, and missile tracking and recovery. During the Berlin Airlift it hauled coal and food supplies to West Berlin. After the Korean War it continued to be used for military and civilian uses by more than 30 countries. It was one of the first aircraft to carry the President of the United States, the first being President Franklin D. Roosevelt during World War II.
The Douglas DC-6 is a piston-powered airliner and cargo aircraft built by the Douglas Aircraft Company from 1946 to 1958. Originally intended as a military transport near the end of World War II, Douglas reworked it after the war to compete with the Lockheed Constellation in the long-range commercial transport market. Douglas built over 700, and many still fly in cargo, military, and wildfire control roles.
The Douglas DC-7 is an American transport aircraft built by the Douglas Aircraft Company from 1953 to 1958. A derivative of the DC-6, it was the last major piston engine-powered transport made by Douglas, being developed shortly after the earliest jet airliner—the de Havilland Comet—entered service and only a few years before the jet-powered Douglas DC-8 first flew in 1958. Larger numbers of both DC-7B and DC-7C variants were also built.
Schreiner Airways was a charter, passenger and cargo airline based in the Netherlands.
Combi aircraft in commercial aviation are aircraft that can be used to carry either passengers as an airliner, or cargo as a freighter, and may have a partition in the aircraft cabin to allow both uses at the same time in a mixed passenger/freight combination. The name combi comes from the word combination. The concept originated in railroading with the combine car, a passenger car that contains a separate compartment for mail or baggage.
Juneau International Airport is a city-owned, public-use airport and seaplane base located seven nautical miles northwest of the central business district of Juneau, a city and borough in the U.S. state of Alaska which has no direct road access. The airport is a regional hub for all air travel, from bush carriers to major U.S. air carriers such as Alaska Airlines.
The Avro Type 688 Tudor was a British piston-engined airliner based on Avro's four-engine Lincoln bomber, itself a descendant of the famous Lancaster heavy bomber, and was Britain's first pressurised airliner. Customers saw the aircraft as little more than a pressurised DC-4, and few orders were forthcoming, important customers preferring to buy US aircraft. The tailwheel undercarriage layout was also dated and a disadvantage.
Trans-Canada Air Lines Flight 304 was operated by a Vickers Viscount 700 aircraft owned by Trans-Canada Air Lines. On July 9, 1956, the No. 4 propeller of the aircraft tore loose from its engine over Flat Rock, Michigan in the United States, during a flight from Chicago, Illinois, to Toronto, Ontario, and Montreal, Quebec; one blade of the propeller sliced through the passenger section of the cabin, killing one passenger and injuring four passengers and one flight attendant. The aircraft diverted to Windsor, Ontario, in Canada, and the pilots carried out an emergency landing. The accident was the first to involve a Vickers Viscount aircraft in scheduled service, and was the first instance of a propeller loss on a turbo-prop aircraft.
The Martin 2-0-2 was an airliner introduced in 1947. The twin piston-engined fixed-wing aircraft was designed and built by the Glenn L. Martin Company.
The Canadair North Star is a 1940s Canadian development, for Trans-Canada Air Lines (TCA), of the Douglas DC-4. Instead of radial piston engines used by the Douglas design, Canadair used Rolls-Royce Merlin V12 engines to achieve a higher cruising speed of 325 mph (523 km/h) compared with the 246 mph (396 km/h) of the standard DC-4. Requested by TCA in 1944, the prototype flew on 15 July 1946. The type was used by various airlines and by the Royal Canadian Air Force (RCAF). It proved to be reliable but noisy when in service through the 1950s and into the 1960s. Some examples continued to fly into the 1970s, converted to cargo aircraft.
Varig Flight 967 was an international cargo flight from Narita International Airport in Japan to Rio de Janeiro–Galeão International Airport in Brazil, with a stopover at Los Angeles International Airport in the United States. On 30 January 1979, the Boeing 707-323C serving the flight disappeared while en route. Neither the aircraft nor its six crew members have ever been found.
On 2 February 1953, an Avro York four-engined piston airliner registered G-AHFA of Skyways disappeared over the North Atlantic on a flight from the United Kingdom to Jamaica. The aircraft had 39 occupants including 13 children.
The Douglas DC-2 is a 14-passenger, twin-engined airliner that was produced by the American company Douglas Aircraft Company starting in 1934. It competed with the Boeing 247. In 1935, Douglas produced a larger version called the DC-3, which became one of the most successful aircraft in history.
Lufthansa Flight 502 was a scheduled flight from Hamburg, Germany to Buenos Aires, Argentina on 11 January 1959. The flight was being operated by a Lockheed L-1049G Super Constellation. On the leg between Senegal and Brazil the Super Constellation was on approach to Rio de Janeiro–Galeão International Airport when it crashed near Flecheiras Beach just short of the runway. All 29 passengers and seven of the ten crew were killed. It was the first fatal accident involving the current Lufthansa since it was formed in 1955.
TAI Flight 307 was a scheduled flight operated by Transports Aériens Intercontinentaux (TAI) between France and the Ivory Coast via Mali operated by a Douglas DC-7C. On 24 September 1959, the aircraft crashed during its departure from Bordeaux–Mérignac Airport, France when it flew into trees. All of the flight crew and 45 of the 56 passengers on board were killed; the other 11 passengers were seriously injured.
