Saucer shaped craft seen June 1960 over Santa Ana, California

I was 11 and I was standing with my family and a few neighbors in the driveway of my home.   We were standing around waiting to get in the car and someone noticed "it".  
My family and neighbor all moved to the end of our driveway to get a better look, as it moved north. We just watched its rotation was marked by the 3 tiered exterior lights.  Making sharp turns slowly, it hovered over what is now the intersection of Main street  and the 5 frwy. 
Comments made were "what is it?".  My mother turned to my dad and said "Mike, it's not a plane or a helicopter" My dad said "....no,it's not a blimp either". We could SEE IT. 
The strange part is that I cannot remember even mentioning this to anyone until I was on a vacation with my sister and a girlfriend. 1991 and we went up to Devils Tower.  We stopped 5 miles short of the turn off, got out of the car, and started talking about the movie "Close encounters...".  I turned to my friend and said " We (my sister and I ) saw a UFO once". 
At that moment, my sister and I talked about it for the first time. We just looked at each other and started telling the brief story, taking turns,and agreeing with the others recollection.  She remembered it as I did.  Our friend was dumbstruct.
Date probably is approximate, although the witness does not indicate that fact.  PD
