I was in my back garden having a cigarette one evening the sky was clear and i was observing the stars. as often the case when looking at a clear sky i spotted a satellite making its graceful pass over the sky i watched as it disappeared into the distance then to my amazement i saw another flying along the exact same flight path. this continued for a few more minutes with a total of 6 objects flying above me. i'm no satellite expert but i'm pretty sure they don't orbit in convoy. these lights were white and red, made no sound and we're flying at an extremely high altitude. where i live we're used to military jets etc in the sky with several us and uk air bases in the area but i have never seen anything like this. please help find me an answer if you can
