UFO Sighting in Calgary, Alberta on June 30th 1976 – seen ufo hovering and then made radical movements zig zag then gone

My friend and I were outside playing and felt compelled to look up I seen a silver metallic diamond shape object blinking lights hovering 7-8 hundred feet above not moving at all no noise. Hovered long enough for me to run in my house a get my mother, the three of us watched it for a couple more min then it suddenly made a zig zag move and was gone, it moved faster than I've ever seen anything thing move then and since. I wasn't scared I felt like I was suppose to see it strangely I've never been able to get it of of my mind. I think I have some type of special mental abilities not sure how it all works? I WISH I could see it again...
