My friend and I went for a walk in the night to look at the stars and chat. We were gazing up into the sky when wee both noticed what looked exactly like a star but it was moving. My friend remarked that it could possibly be a satellite. We continued to watch it moving at a moderate speed and then suddenly changed course (path like a sharp angled L). We were both stumped by this, we both thought it impossible for a satellite to change course. After that it simply disappeared. The details are sketchy in my memory, as this happened quite a few years ago. I cannot recall whether it was blinking or not, but imagine that it did. All I remember feeling was suprise.
