Great Falls Daylight Film Report (1950)

August 15, 1950Great Falls, Montana, United States

Hynek discusses a classic daylight photographic case from Great Falls in which motion-picture film recorded two point-like lights in a bright daytime sky. The Phase-2 source passage does not establish a stable hull shape, so ANOMALY preserves this as a filmed Daylight Disc-class report rather than inventing a physical craft morphology.
