Help with identification object please - possible drone sighting the Netherlands 19 december
Location: the Netherlands, 52.012400,5.092700
Time: 17.32

Please help me to identify 1 of the objects I saw. Last night was the first time I've noticed it wasn't as cloudy here and I was able to go out and take a look. I've seen 6 flying objects with flashing lights (drones?) at 2 different locations, around 17.30 -18.20, flying by themselves not in formation and not manoeuvering in any special way, and 1 looking out of our window at 21.39, so 7 in total. I've checked flightradar24 each time, and as far as I could tell there weren't any planes flying at that time at that location. Excuse my enthusiasm in the video, I'm just really curious (and anxious to be honest) about everything that has been going on. Perhaps people just really love flying drones here in Nieuwegein, and I just haven't noticed it before. That would be entirely possible. As I am totally new to all of this I have no idea what normal flying heights are/look like in the sky. So it could be nothing, mods please delete this post if this is nothing, I don't want to muddy the waters. Or maybe leave it up to educate newbies like myself :) I'll start with this first one, it had flashing lights. Love to hear what you think and would especially love to hear from fellow Dutchies if they have seen anything similar in their surroundings.
