Circumstances:
The aircraft was completing a charter flight from Rome to Montreal with intermediate stops in Paris, Shannon and Keflavik, carrying a crew of seven and 51 Canadian pilgrims flying back home after a pilgrimage in Rome and having seen the Pope. While cruising by night at an altitude of 6,000 feet between Grenoble and Gap, the four engine airplane hit the east slope of the Mt Obiou (Grande Tête de l'Obiou) culminating in the attitude of 2,789 meters. SAR operations were quickly conducted but several hours were necessary for the rescuers to access the crash site that was difficult to reach. The wreckage was found in a snow covered terrain and all 58 occupants were killed.
Crew:
Orville-Alfred Olmstead, pilot,
Robert-James Henderson, copilot,
Henry-Thomas Warkentin, navigator,
Arthur Bethwell, navigator,
Dennis-Norman Nichols, radio operator,
Roderick-Malcolm McIsaac, purser,
Helen-Marjory Johnston, stewardess.
Probable cause:
It was determined that the aircraft deviated from the prescribed flight path by 80 km too the east at the time of the accident, due to a strong wind blowing from the west. It was reported that the crew apparently realized his wrong position and tried to correct his route but too late to avoid the collision with the ground.

Circumstances:
After its departure from Lyon, bound for Istres and flying south of Grenoble in poor weather conditions, the aircraft hit the slope of a mountain located in the Dévoluy Mountain Range. SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the crew was found. The wreckage was localized by walkers on September 26, 1946, at an altitude of 2,700 meters, in a craggy area located between the Petit Obiou and the Grand Obiou. All 11 occupants were killed.
