I had gotten off work and went out on my side porch when I happened to look up and see them moving back and forth. They were green (almost a luminescent color).I just stood there in awe and watched them fly over. I asked myself about what I had just seen and before I could get into my my front yard, they had disappeared. I wrote a letter to Mufon and have yet hear anything back. My house is 1/4 mile from Offutt AFB, which was Strategic Air Command at that time. I now can't remember if the year was 2003. I had a friend die in the year this occurred. My oldest son's birthday was that day.
