UFO Sighting in Vancouver, Washington on July 4th 2015 – Two sighting by four family members within 1/2 hr or so. Backyard on 4th of July

On the 4th of July at approx 10:30 pm my father and brother-in-law were outside and described seeing an orange "firey" looking "something" go across the sky. We were out talking about it and we looked up and another flew by. We were facing North. Then another went by, silent following the trail of the first. We went inside. About 1/2 hr later, my Mother-in-law and I went to the backyard (the first sighting was in front), and we saw another, a third, going in same direction, same path. Almost like an instant replay. At the time of the first two, there were fireworks in the area, but it was far above the neighborhood display. The third time, the sky was clear. I saw someone else from the area had posted this same thing. I never thought it was fireworks of any kind because it seemed like it (they) followed it's own trajectory above the exploding fireworks, seeming well above and a lot larger and there were no characteristics of fireworks other than it was bright and orange.
