When I first saw them I thought it was 3 helicopters moving in my direction. As I watched them for awhile (3 -5 minutes) and it appeared that the one closest to me was flickering and then a 4th one joined in line. There was 4 total that I saw that had a fireball like appearance. They were larger and closer then the stars you could see on this clear sky night. I walked over to get my wife and ask/show her, but when I returned they where gone. We stood looking trying to figure out what it was. In a short time later a fellow came up asking if I saw the strange lights in the sky. He said this without me saying anything about what I saw. I told I'm I did and he went on to tell my wife and I the same story I just told her. I wish I stayed and watched after he said that 2 went one direction and 2 the other. Sadly I missed that. The funny thing is we live near an airport and see many types of aircraft all the time and know it's not unusual to see them lined up. But we are not at home and these weren't plains lining up to land. I'm not sure what it was. But fell strong enough to know thieves 4 lights were different.
