Summer of 1976, San Diego, CA, visiting Father stationed in CA for 3 weeks. One evening saw large red Triangular shaped object.

During the summer of 1976, my brothers and I had gone to CA to visit our father for 3 weeks.  At that time he was stationed in San Diego CA.  One evening, my brothers, stepbrothers and stepsister had all gone out to play in the cul-de-sac after dinner.  It was evening and the sun was beginning to get low in the sky.  While playing, I do not remember who, someone noticed a large red triangular object in the sky.  I remember that the altitude of the object did not seem to be very high because I noticed that the object had 3 inverted "V's" on what appeared to be a flat bottomed triangular shaped object.  We all stood and watched the object disappear into the horizon.  I cannot even begin to guess the speed at which the object disappeared, it was amazingly fast and was gone in just a second or two.  The object then reappeared again, coming back from the direction it had disappeared, it again flew directly overhead, never making any sound, disappearing into the horizon from which it had originally come from. I am sorry I cannot provide more information, It was the summer of 1976 around the time of the summer olympics.  We were a bunch of kids out playing, the youngest of us was 7, and the oldest was around 16.  There may even have been a few neighborhood kids playing with us as well. I honestly do not remember. I have never forgotten what I saw that day, I remember thinking that it looked like someone was taking it out for a test drive. The object appeared to me to glow a very bright red.
