On October 21, 1977, two witnesses in Betheny observed an elongated, luminous object crossing the sky. The object emitted multiple colors and left a fading trail behind it before disappearing behind the landscape. Although the phenomenon was clearly observed, no additional testimonies or records were collected, making it difficult to determine its nature. The lack of supplementary information complicates further analysis of the case.
