Was on a 10 minute break from work, was in the smoking shelter, noticed something moving, saw a square shaped object spinning whilst hovering and moving at the same time, had 4 bright orange lights in each corner and blue lights towards centre. I didnt know what it was, i also tried to take a photo but my phone froze and would not work. I showed the one girl next to me and we both just stared at it. Felt shocked, confused and could not believe my eyes. It just disapeared behind trees.
