Square blue/white building-block-looking train with approximately half dozen blocks/cars

Tuesday evening, July 11, three of us sitting around a campfire listening to music on a portable radio. All of a sudden the radio started acting up with sound going in and out. One of us happened to look up into the sky and yelled, “What is that?” It looked like a train with large square cars attached evenly spaced, about 1/2 dozen squares. Each square or cube was quite large, bigger than an airplane, and there were no red or green running lights pulling it…Just a bunch of squares evenly spaced and attached like train cars moving slowly across the sky. Each square mostly white with blue haze against dark sky and no sound. We had limited view of sky through tall pine trees, but it was directly overhead. The “square train” was traveling west to east at 10:15 PM. Now each night for the rest of the week we all keep looking up at the sky. The following Sunday, we witnessed what looked like your pictures of space x star link passing through our viewing area which was different in shape and size. The first sighting on July 11, was lower, wider, and much larger in the sky, but moving at about the same speed with no sound. We would like to know what we saw.
