🇺🇸 USAF — Project Blue Book
In May 1966, a witness in Mobile, Alabama, observed five objects in the sky appearing alongside pink-tinged cotton ball clouds. The moon was not visible during the sighting but became visible the moment the objects disappeared. Investigators concluded that atmospheric conditions—such as scattered clouds, light wind, and possibly smoke from a paper mill—caused a partial blackout of the quarter moon from the observer's location. As the cloud mass moved, moonlight shining through varying cloud densities may have created the illusion. The phenomenon lasted 50 minutes and was classified as likely astronomical or natural.
The Air Force report included testimonies and weather data, such as temperature and wind direction. Although no photos or physical evidence were collected, the combination of environmental factors was considered to explain the witness's experience. This case, like many from the era, was archived under Project 10073, an initiative to study unidentified aerial phenomena.
