UFO Sighting in Missouri on July 5th 2015 – Standing in my yard and 2 fast moving objects in a line flew overhed.

1. My fiancee, her mother, and myself had just finished setting off fireworks and watching the neighbors do the same. We were all 3 standing in our front yard. 2. My fiancee's mother seen the first light and commented on how fast and orange it was. 3. My initial thought was a fighter jet because of the low altitude, high speed, and straight flight path. 4. The first object was traveling at a high rate of speed in a sraight line. South to north. My guess is that it was about 1,500 - 2,500 feet up and moving close to supersonic. Trailing behind the 1st object by approx a 1/4 mile was an identical object moving at the same rate and in the same direction. No flashing lights, only a solid orange glow. It was dark so we couldn't see any of the surface of these objects. Only a bright orange light. 5. I felt confused by what we were seeing. Ive been to several air shows and have loved planes all my life, so i was trying to figure out what it could be since there were no strobes and no sound coming from these objects. The rate of speed stumped me for there being no sound. 6. Both objects moved straight north until we lost sight of them over the tree line. They appeared to have possibly gained speed after being past overhead.
