Twenty one orange red objects observed over a period of 20 minutes traveling due north.The objects were orange red circular shape with a single flashing light toward the front of the craft.The trajectory was about 3/4 miles to the east and direction of travel was due north at an altitude of approximately 1,500 feet. A relative was to come for a visit, so the camera was being watched in order to open the gate when they arrived, the lights were first noticed on the monitor. My wife's cousin and her husband saw these objects about one mile away as they approached our road, they were traveling west on hwy 16. They all stood outside and watched the last three as they passed to the north. The last pair of objects stopped forward motion for a short period of time. I was not at home and did not see this firsthand, however a DVD copy was made from the video recorder, I counted a total of 21 objects, single, two at a time and in on group there were three in close proximity to each other. They were observed from 19:09 to 19:25, speed was relatively slow and at a constant rate, no sound was emitted, they were silent.
