My friend has a house on the outskirts of congress, arizona. from the front yard you can see the milky way and a good amount of the stars, there are no city lights. looking up as i was smoking a cigarette, i noticed a light slowly moving across the sky. at first i was thinking it was a satalite, because it seemed to far up to be a plane. plus the light was just a white light if it hadn't have moved, it would have looked like a star. as i was watching it i noticed another one directly below it moving in perfect formation. then as i looked at the 2 lights i noticed a third one in front moving perfectly with the other 2. then i could see as it was moving across the sky the stars were being blacked out inside this triangle shape. i ran inside and told my friend to come and look at this ufo moving across the sky. he came out and when he and i got sight of it again, it turned from moving westward and moved straight up, very smoothly and slow, it then just faded into the stars. my friend has been on that property and his family before. he said that stuff doesn't even phase him anymore, his dad and himself have seen countless unexplained things in the sky there. from what i could tell whatever it was, was very very big. i have no idea how big, the sky was cloudless that night, but my guess on its size would be at least the size of a small city.
