Black dark mass , cylindrical shape, no lights. Silent. Came up one side of the horizon and we said what the heck’s that. Thought maybe a balloon but quickly realized it’s speed and it’s not a balloon or airplane. As it was above us it was difficult to spot it - blurry dark mass but as it continued across horizon it became visible again. Seemed to have a blurry halo as it faded away. Took all but 10 seconds. Wtf.
