In Nov 2002 about 2AM i was on a Training mission with my unit near Fort Irwin, CA. We were unloading vehicles off the rail trains. We moved to the paved road leading to the base. I looked up and noticed a luminous multi colored smoke trail that zig zagged through the sky. It appeared to explode in the sky but no sound or debris was heard or scene. As I said "What the heck is that", high ranking Military officers appeared from know where to say "It is only a missile test". My unit was Air Artillary and we high a high trained unit that has to detect all Foreign and Domestic jets and missles. Know one from my unit had ever scene anything like this.
