Three black points and a white shape in the sky

Summary

On October 5, 2016, at sunrise, a witness observed three black points that approached and formed a conical shape. After it disappeared, a white elongated form appeared in the sky and remained motionless until 11:30. The witness took photographs, but no other testimonies were collected. According to the investigation report, the hypothesis considered was that the points might have been three migratory birds misperceived due to poor optical quality and distance. Although the testimony is weak with few usable details, there are 15 photographs, though only some were analyzed. Processing with tools like IPACO supports the bird hypothesis, despite the low image quality.
