Christopher D witnessed a solid red and green object moving about the sky and hovering in mid air, with a spotlight trailing it. This doesn't sound like a typical plane or fireworks show to me? Here's the full testimony, kindly submitted to Texas UFO Sightings:
Saw a red and green object (non flashing) in the sky being spotted by a spot light, then the spot light shut off. Object hovered in place for a while then flew closer to Boerne stopped split second and hovered for several minutes before flying south west again.
No doubt many Texans saw strange things in the sky on July 4th, but if you saw something a little more extraordinary than fireworks - like, a UFO - report your sighting!
