🇺🇸 USAF — Project Blue Book
In August 1949, a Seattle resident reported seeing four objects flying in formation. The witness, a mail carrier with aviation experience, described them as flattened silver discs with a dark border. They left no smoke or vapor trails and vanished within seconds. The official report concluded they could have been jet aircraft, though the witness did not recognize them as such.
The investigation was conducted by the USAF, which interviewed the witness and a second person. Although the second witness couldn't see the objects due to a visual obstruction, the first insisted they didn't look like conventional planes. The report found no physical or photographic evidence but noted the witness's credibility. The case was ultimately closed without definitive conclusions.
