Hi @physicfactor,

You're talking about multiple things but really I can see only one white dot flying with steady speed in straightforward direction.

Based on your posts my guess is that you are from Germany, but at least from western Europe.

If it is in fact was one object, and you are from west Europe, that object could have been the International Space Station (ISS) which have flown over wester Europe in the early morning hours today. (around 7:10-7:20am CET)

ISS has a fast moving, very bright star-like appearance because of the reflected sunlight. Also the flying speed seems similar too. The station's orbit time is 92 minutes so it's pretty fast:)

Next time if you have an observation please write down the place and time so it would be much easier to check. Also when you make your video and zooming in, you want to support your hand on the side of a pole or wall so it won't be this shaky.

Mention my name @neander-squirrel if you see this phenomenon again, please:)

If you have an android phone, you can check out the ISS Detector app which tells you when to look at the sky to see the space station.
