2 adult men saw 2 bright objects, each appearing similar to but larger than full moon

Looking to the north from parking lot, at about 45 degree angle inclination off horizon, two large moonlike bright round objects, same color and shape as full moon but larger, about the same brigthtness as full moon on a clear night, were seen blinking at each other at same altitude. (Objects separated by apparent distance of 5 in.as measured between thumb and forefinger at arm's length). Estimated distance several miles? Not sure. The two objects did not appear to be connected but seemed to be blinking to one another possibly in communication or coordinated somehow. One witness was frightened and went indoors immediately after seeing the objects. The other witness watched the objects for several minutes. A separate object was seen in the sky during this sighting, it was a LifeFlight helicopter according to the witness who had stayed to watch. After the LifeFlight helicopter left the area toward the west, the two large round blinking objects soon blinked out and did not reappear. There was no sound associated with the blinking large objects although the LifeFlight helicopter had made normal helicopter sounds. Moon was not in the sky at time of sighting, had set around 3 pm and was due to rise after 11 pm. Witness is 62 years of age, does not drink alcohol. He did not have his glasses with him, but could see the round objects quite easily because of their brightness and large round shape. He thought it appeared like "two full moons" even though he knew it was not that, and even though the moon would have been in the southern sky so he knew that was impossible. He doesn't believe he had any problem of "double vision."
