Background
Five aircraft were returning from Los Angeles, California, to Abbotsford, British Columbia, Canada. The flight crews obtained weather information during stops at Crescent City, California, and Newport, Oregon.
Flight and Weather
After landing at Everett, Washington, one of the flight crews filed a flight plan for all five aircraft. At that time, the crew was asked if they wanted a weather briefing, but they indicated they had already received a briefing for the route. The pilots also obtained weather information from a computer in the lobby of a fixed-base operator (FBO) at Everett.
After departing Everett on a night flight to Abbotsford, the flights encountered deteriorating weather with snow and clouds. The flight crews of two aircraft reversed course and landed at an alternate airport. The crew of a third aircraft diverted, went over water, and then continued en route.
Accident
The two remaining aircraft, C-GJNM and C-GIXI, collided with mountainous terrain about three miles apart. C-GJNM impacted on wooded terrain at an elevation of approximately 2,100 feet. About 11 miles northwest at Bellingham, Washington (elevation 158 feet), the 1950 weather was in part: 2,100 feet broken, 10 miles visibility with rain, wind from 240 degrees at 6 knots.
Wreckage
The wreckage was found the next day covered with snow.
