First sighting just now in Berlin
Time: April 18, 2025 12:15pm
Location: Berlin, Germany

This thing just flew across the back of my terrace. It was about 20 to 30 m away by the time I got my video on my phone working it was a bit further. At first, I thought it was a balloon, but upon closer inspection it looked more mechanical, so I thought maybe it was a drone, but I’ve never seen a drone with this sort of angular shape before and I didn’t hear any rotors which I would’ve heard because it was so close. Unless this is some kind of silent drone I’m unaware of? Do you know what this is?
