I was stood at my front door smoking a cigarette in the middle of the day in dec 2015 when i saw a mirrored sphere moving across the sky, it did not leave a trail like a plane and was not a helicopter it was silent.It was not really fast and made no strange movements but was unlike any craft I have observed before. Then approximately 1.5 weeks later I saw another. I wonder about the universe so often just look at the sky and have never seen anything bizarre until now! The first thing I saw was a ball like craft moving across the sky, then I noticed that there was no trail like you get with aeroplanes. I watched it for quite some time until it was out of sight. Its motion was very smooth but was powered by something as it was moving across the sky and not up in a vertical manner. I felt calm and was not scared at all, I just watched it until it disappeared. I told my partner after he returned home.He does not believe me.
