Large string of light move slowly from west to east, very low and silent

It was late at night, early morning, me and my cousin were outside playing.  My cousin said what is that, so I turned around and looked up in the sky.  I saw an airplane pretty high in the sky and said an airplane and turned back around and he said no look lower.  I turned around again thinking he was pulling my leg, but this time I had to look for a second and then I could see it.  It was very low to the ground, maybe 150 yards up and very close to us.  The first thing we did was run to it.  It was moving very slowly from West to East.  It blended in with the night sky, with a few exceptions.  We ran directly beneath it and looked up at it.  It stayed at a constent speed, very slow.  It was long, about 50 yards from our view point, looked like a string of lights or string of stars moving through the sky. The one way to know for sure that there was something there was to look at the stars in front of it, while we were beneath it and watch it move over them, the stars would disappear and the lights that looked like stars would just be moving along at the same speed.  It looked to me like it was reflecting the image of the stars above it to the bottom of it.  Some of the lights would twinkle a little.  I seam to remember som kind of round windows on the side but am not sure.  I could not tell the exact shape since it was the exact same color.  You could tell that it was one very big object and it was silent.  It didnt slow down or speed up, we walked under it for about 10 blocks until the T in the road.  We watched it slowly go over the factory at the end of the road and went back to the house.
Date is approximate.  PD
