Spherical UFO observed in Moselle in 2012

Summary

In April 2012, a witness in Moselle observed a gray spherical object moving under the clouds. The object left a trail of white smoke or flames and moved in a straight line. Although initially intriguing, the case was classified as likely a festive balloon due to its behavior and trajectory. The occasional reflection of sunlight by the object and the lack of other testimonies support this explanation.
