- Den 9 december 1956 saknades Trans-Canada Airlines Flight 810 i en storm, på väg från Vancouver till Calgary.
Den förväntade platsen för försvinnandet var Silvertip Mountain och det omgivande området Skagit Valley. Med 62 personer på spel och ett nytt snöoväder som täckte bergen varje timme växte desperation för att hitta något tecken på flygplanet.
Veckan efter försvinnandet visade sig vara en skrämmande besvikelse för de många som sökte både på land och i luften.
- Efter en tid antogs att alla inte hade överlevt på grund av ovädret, men passagerarnas familjer höll fast om hoppet om deras näras överlevnad.
Fem månader passerade utan några nyheter om flygplanet, fram till den 12 maj 1957, när bergsklättrare Elfrida Pigou tillsammans med två andra klättrare upptäckte delar av flygplanet nära de bergtopparna i Slesse. Under de närmaste dagarna efter upptäckten tog många människor, inklusive reportrar, sin väg uppför Slesse sluttningar för att ta reda på mer om kraschen.
Vancouver Sun reporter, Fips Broda, skrev:
“Not one of the sixty-two persons aboard the Trans-Canada airliner on December 9 suffered even a split second of agony when the plane crashed. I stood beside the wreckage of that crashed North Star and I can tell the families of those aboard the plane that nobody lived beyond the moment of impact. I am sure from what I saw at noon Tuesday at the top of Mount Slesse that the aircraft exploded the second it struck. All those inside died instantly.”
Det var den dagen då offrens familjer äntligen skulle få nyheter som de visste var sanna, men hoppades att de inte skulle behöva höra. Sextio år senare, vi kommer ihåg dem, när vi tittar upp till berget, står höga, över vår stad; Den sista viloplatsen för de 62 personerna ombord på North Star.
Flight 810-9 was a scheduled flight from Vancouver to Toronto. It carried a crew of 3 and 59 passagers. A cruising altitude of 19,000 feet was selected. The aircraft departed Vancouver at 1810 hours Pacific standard time on 9 December 1956 and was cleared by Air Traffic Control to Calgary Airport via Mud Bay, Abbotsford and Cultus Lake (Red 75 and Red 44). The flight made the normal position reports giving altitude and reported icing beginning at 16 000 feet, moderate turbulence 16 000 feet to 18 000 feet, heavy jolts at 19 000 feet and at 1848 requested clearance to 21 000 feet. At 1852, 810 reported a fire in No. 2 engine, that this engine had been shut down and that the aircraft was returning to Vancouver via Cultus and Abbotsford. Shortly afterwards the flight reported difficulty in maintaining height and requested clearance to descend on Green 1. The last altitude reported by Flight 810 was just above 15 000 feet which would be maintained if possible. At 191 0 hours Flight 810 reported passing Hope, the altitude was not given but clearance to descend to 10 000 feet was requested. ATC cleared 810 to cross the Vancouver range at 8 000 feet or above. Flight 810 acknowledged and this was the last radio contact. All through this latter part of the flight the tone of the voice in the radio transmission, as recorded on TCA tape, did not suggest undue concern by the crew of 810. Nothing more was heard of the aircraft until a part was dis- covered by mountaineers on 12 May 1957, when they .were climbing Mt Slesse, at approximately the 7 600-foot level, adjacent to the third highest peak.
Probable cause: The cause for the aircraft being at an altitude low enough to strike Mount Slesse is undetermined, but there is a high probability that the aircraft, while flying on 3 engines, encountered either severe icing, turbulence, subsidence, or a combination of all three, or suffered some other difficulty of such a sudden or dire nature that the crew were unable to communicate with any agency or control the aircraft. For undetermined reasons the aircraft was not on Green Airway No. 1 to which it had been cleared by Air Traffic Control. The following factors contributed to the accident:
- Loss of engine power No. 2 engine shut-down, fire suspected,
- Existence in the area of known subsidence, severe turbulence, and moderate to severe icing probably in the lower levels.
