My father and uncle were installing a tv aerial on our roof. My mother, brother, sister and I were watching. Suddenly behind them we saw 6 white disk shaped Ufos speeding up into the sky at a 45 degree angle in a perfect line. The sighting lasted about 5-10 minutes. The Ufos were flat on the bottom and round on top. My mother was frightened as we pointed to them but she would not allow us to alert my father. I was not afraid nor was my sister, but my brother was scared. He was the youngest. My mom never reported this nor allowed us to discuss it.
