I saw something similar when I was living in northern China and it did intrigue me some what. Interesting however that the locals were all nonchalant about seeing the same. Later I discovered that all it was was a kite flying at night with lights attached to it's string thereby causing the row of flashing lights all in a straight line. I felt disappointed after having discovered that. I was hoping it was a UFO or something.
I'm not sure whether this is the same as what you saw. I was at ground level, looking up, when I saw them.
