I was in my house, windows open when I heard a loud helicopter approaching. I ran out on my back porch and saw a red light or orb high in the air fly directly over my house from east to west, then a low flying helicopter following behind it. They were both flying exact same direction at about the same speed but the copter was much lower than the light/orb. They flew out of sight, due to trees the observation was approx 10 seconds. Unable to see color of copter due to darkness but it was large, and very loud, it also seemed to be much lower than the object and followed directly behind it. I have no idea what it was, id did not have an outline which made me think it was just a light or orb, it traveled straight and had a consistant speed. I felt afraid as if the military was chasing this unknown object. After it passed and was out of sight I went up to my wife and told her but she laughed. I know what I saw and it wasnt a plane, or another copter, it didnt seem to make any noise as I just heard the noise of the copter. Lost sight of the object through the trees. It happened too quick to video and I was kind of in awe of what I saw and didnt even think to grab my phone.
