🇺🇸 USAF — Project Blue Book
In March 1960, two military pilots reported seeing three white lights in a horizontal formation with varying intensities and movements. The objects, grapefruit-sized, appeared at 5:30 AM and remained visible for 5 to 6 minutes. Witnesses noted that the lights were brighter than surrounding stars and ground lights, causing confusion about their nature. The key clue was the mention of a haze or inversion layer, suggesting the lights were likely a mirage of bright stars or ground lights. While other explanations like balloons or aircraft were ruled out, the report concluded the phenomenon was likely optical in nature.
