Weather was clear skies, no clouds. Me and two other men in their 60’s witnessed what seemed to be a triangle shape craft the size of a football stadium moving slowly and silently across the sky. It had 3 lights one at each point but appeared to be cloaking itself and when the lights blinked it was like you could look through the center of it. That , or it was projecting a picture of the sky and stars to blend in/camoflauge itself. It had no sound whatsoever and I’m baffled at how something so HUGE could fly. I’m quite freaked out thinking about what could possibly be on that ship.
