We get spoilt in Manchester. We never get let out without our carer when there are strange lights in sky. Especially just after closing time.
Having said that, I did see Three strange white lights in the sky a couple of weeks ago. At first they seemed very close together. After a few minutes they started to move further and further apart. The closer they got to me the further they moved from each other. The only one that didn't move was the central one. Then as they got closer I could hear a low noise, this quickly built to a deafening roar. Turned out to be a KLM Fokker 100 on finals for 23R
But keep watching. There out there. KLM Fokkers I mean.
