To describe this formation as a ‘triangle with drone’ seems fanciful, because we don’t know what it is, except that these are very clearly unknown objects in the sky over Norway. It is difficult to believe that the triangular pattern is, for example, a flight of ultralight aircraft, because it is manuevering so precisely that the lights could even be on the corners of a single object. Strong video.
