I was watching fireworks and saw a bright red light and figured it was an airplane. I suddenly noticed it wasn't getting any closer or further away. I grabbed my cell phone and tried to videotape it, it was very dark outside and had a hard time with seeing if it was showing up on the video. Standing on a chair I tried to get it on video. I finally, after about 2-3 minutes, decided I could probably see it much better from the backyard. Sure enough, I could see it! I told my son to grab his phone and get on the trampoline and video tape it. As he was taping I was watching it, it was a bright red light with blinking green lights. when the fireworks would get too close to it, it would hover down and to the right so that it was behind a tree branch and I could barely see the red light between the branches. When a firework would go off to the right, it would hover back up and over to the left. It was able to move straight up and down and also at angles, and pretty quickly at that. After about 5 minutes or so, it just descended sharply and it never came back. I was in and out of the house for about another hour and never saw it again. I'll be watching for it tonight, very curious to find out what it was!
