saucer over Angel Stadium summer of 71 or 72

It was the summer of 1971 or 1972 I was a small child about 6 or 7 I was in my backyard playing when I saw a silver saucer with different colored lights around the edge. Watched it fly north along the 57 freeway about a mile from where I was. Went in the house and started drawing pictures of the new kind of airplane that I saw in the sky. When my mother asked what I was drawing I told her that it was an airplane. She said airplanes don't look like that. I said the one I just saw did. We went outside, but by then it was gone. The sky was clear, and there was no mistake what I seen.
