White square-shaped UFO over Bristol

On November 29, 2018 at 14:30, a witness saw an unusual white square-shaped UFO over Bristol, United Kingdom.

Witness report:

I took a photograph of an interesting cloud formation at the front of my house. when i looked at it later i noticed an unusual shaped object. when i zoomed in it looked like a single tier wedding cake. the base and the rim stood out from the rest. i was most fascinated with this object and i think you could rule out this being a small cloud. on sep 12th 2019 i filled out sighting report. ( 103252) i made a mistake and failed to send the photos, so i will send them as well.
