Was outside smoking a cigarette and looked up in the sky and seen an Orb v-like formation was flying low and slow. No sound and very dim orange glow to it. Was not symmetrical and based on how low and slow it was flying didn't appear to be man made. USAF Eppley Airfield is only a 20 minute drive to the North east of where I was at the time. Not long before a thunderous flock of blackhawk helicopters were flying in the same path, but this was during the day. Somewhere between 15-20 helicopters. Thought we were being invaded, hard to believe it was some sort of training exercise, if it was it wasn't a cheap one.
