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]

Accident

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]

Aircraft

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]

Passengers and crew

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.

Aftermath

All passengers aboard the aircraft were never found. The Douglas DC-4 was presumed destroyed beyond repair.[1]

Probable cause

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]
