Black Triangular Shaped UFO in Germany on October 1, 2023 (Published Today)

The witness stated the following: "Today October 1st 7PM CET my friend and me spotted a weird unknown object flying though the sky of Karlsruhe, Germany. The video shows a paper glider-like object (at least seems like it). At some point it rotates around which make me really wonder what it can be.
And I am not even joking, after I made that video my phone restart and after it restarted I got a camera error which I never had before. I guess it was because I really stretched out the zoom feature.."
