Octobert 31, 2015 or 2016 don't really remember the exact year. it was october 31 as i was out with my nephew taking him trick or treating. we walked past a man approximately late 20's early 30's who was talking on the phone and looking into the sky directly above us. i heard him tell the person he was taliking to, to look up in the sky, which i did look up. i don't think i still believe what i observed. i could baretly make out an extremely dark enormous triangular shape, which appeared to be thick. this object is way way way bigger than a stealth bomber, which i am very familiar with from working on an air force base. the object had no sound and no lighting to it. the object was moving extremely slow in a direction toward las vegas from kingman. you could only make out the shape due to the sky and stars being covered by the object as it floated across them. curious if anyone else has reported this on the exact same date?
