I saw some unidentified flying object in the sky at 03:45 UTC on 08.Oct.2018 passing over Kassel, Germany, in the direction west-west-north. It appeared to go as fast as most passenger jets appear to go in the sky, perhaps a Little bit faster. It was very bright in the night sky, brighter like other stars and diffuse. I couldnot identify it properly. I noticed at flightradar24 some airliner which was heading in almost the same direction just a half Minute later. It was the only airliner in this Region close to that object: KLM810, Registration PH-BQK. It must have seen This object. The visibility was very good. I ve got photos but the object is only a small white patch. I ask myself if pilots of one of this airliner could see something. The ISS was at this Moment somewhere over Pacific Ocean.
Thanks for help.
