Science Questions

I often see lights in the sky when I'm driving. Are they aeroplanes or are they UFOs? Joey

(Nick) Statistically, 85-90% are usually explained by normal things such as planes, weather balloons or satellites. Driving is also a difficult situation in which to make an accurate judgement: not only is the car moving, but you are also seeing the lights through glass, which can lead to distortion.
