In a short time the two satellites are accompanied from 8 Flashes or objects, who are making this Flashes. The sky is a center for traveling objects. Are there satellites at all or what are them? ESA cannot give us an explanation.
On my channel de YouTube you can see the video from the Herschel and Planck satellites, with their escort from 8 UFOs or Flashes.
In the video you can see step by step the flashes appearing and disappearing.
Take a look at the video.Thank you
