A silent, blue oval appeared, flew east at high speed, then vanished.My friend and I were outside walking through the neighborhood one night, and we came to the back of the local elementary school where we sat down for a while. When we got up, we began to walk across the large field in back of the school. When we got to the middle, I felt something strange and I looked up in the sky and as soon as I looked, a bright blue oval appeared from nowhere exactly where I looked. I told my friend to look and we stood there and watched the object fly across the sky. It was going very fast, probably several thousand kilometers an hour and it made absolutely no sound. Overall, the object appeared, flew east and disapeared. We decided to stay there to see if it would return. A few minutes passed, and we observed a helicopter from the airbase fly halfway to our location and then return. Someone else must have seen this.((NUFORC Note: Witness indicates that the date of the incident is approximate. Witness elects to remain totally anonymous. PD))
