🇺🇸 USAF — Project Blue Book
A civilian witness in Mecca, Indiana, reported a strange aerial phenomenon in 1957. A square object measuring 50x50 feet with flashing red lights and a hissing sound was described. Although it might initially seem like a UFO, investigators concluded it was likely an aurora. The lack of precise data such as elevation and observation duration complicated the analysis. However, the described features align with natural atmospheric phenomena.
