UFO Sighting

This happened about 2 years ago about mid-afternoon while driving home with my wife and a friend. This was in Covington, Louisiana the other side of the lake from New Orleans for those who do not know the area.
Anyways what caught my wife's eye first was a dark colored military chopper with mounted guns. This we had never seen there before and it had no numbers or insignia to be seen. By looking in the direction it was heading we then saw a good size silver ball stationary 1/4 to 1/2 mile away. I,m guessing it was more or less the same size as the chopper. Since I was driving at the time at the time I could only get quick glimpses, but my wife said when the chopper got almost to the object it seemed to unable to move forward anymore as if a field was holding it back. This lasted just a few seconds then the object just disappeared and the chopper was again able to move forward. Have no Idea what it was but I know it was not a balloon.

i believe this.
i think at night they shine like stars, but flashy and multicolored. i could be wrong, its only a presumption.
i wonder, if maybe it didnt disappear, but only hid in plain sight.
extremely interesting. thank you so much for sharing.
