UFO Sighting in Hamburg, Hamburg on 2017-09-09 00:00:00 – Orb passed abeam rolling stones event event (100,000 audience), at low level

The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:

I am a trained aeronautical engineer, and pilot. i can a interest in ufos and am very familiar with information on youtube.

i was waiting for the rolling stones concert to start. i noticed this grey orb passing above and abeam the stadtpark . it was definitely not a balloon, bag, uav, drone – it was definitely a orb. i have never seen personally such a object (except on youtube)

its showed no interest in the event. it maintained height, but appeared to drift with the wind as if a balloon (but was not a balloon).

i pointed it out to my friend.

no one seemed interested – as it was simply a orb.

i maintained visual contact until it was too far to see.

theoretically 100,000 witnesses (because of rolling stones concert) – but it was boring and uninteresting to look at.
