🇺🇸 USAF — Project Blue Book
In April 1954, a woman in Annapolis, Maryland, observed three mushroom-shaped objects with a yellowish color flying in formation. The objects emitted a blinding flash before disappearing. The observation lasted between 10 and 15 minutes and was confirmed by a pilot in the area. A curious detail is that a radio transmission tower was being built in the same location, with welding ongoing at the top, leading investigators to consider the possibility that the phenomenon was related to welding activity. Despite the detailed description, there was no physical evidence or photographs.
