🇺🇸 USAF — Project Blue Book
A bright green object was observed slowly descending over Sitka, Alaska, on March 17, 1958. The sighting lasted between 1 and 5 seconds and was reported by a civilian witness. Although the available information is limited, researchers considered the possibility that it was a fireball, a meteor phenomenon caused by objects entering the atmosphere. There were no photographs or radar data, making a more precise evaluation difficult. The report references other documents and studies, such as Dr. Olivier's report, indicating that this case was analyzed in the context of similar sightings.
