Spherical UFO seen in Alberta in 1950

Summary

A witness in St. McMurray, Alberta, reported a round, silver object measuring 4 to 5 feet in diameter on April 9, 1950. The object was observed for less than five minutes and quickly disappeared to the east. Although no photos or radar were used, the report suggests it could have been a weather balloon launched from Grande Prairie. The object's description and rapid movement generated some uncertainty, but investigators considered this a plausible explanation.

The location and short duration of the sighting limited the possibility of a more precise evaluation. However, the civilian testimony and detailed description of the object are valuable for understanding reports from that era. Despite the lack of additional data, the case was filed with the hypothesis that it could have been a balloon, which was common in the 1950s.
