Single orange light moving very fast W to EMy husband and I went onto our back deck to let the dogs out. We noticed the sound of an airplane, the small kind that only one or two people can sit in. We noticed a bright orange light moving very quickly over us in a straight line West to East. At first we thought it was the plane we heard, but as it sped across the sky, we realized it wasn't. This object had no blinking lights. It was bright, like the size of Venus on an early spring morning, but orange in hue. With a full moon tonight, the clouds were illuminated, and this object was flying beneath them. It was out of sight within 15 seconds, miles and miles away, but we still heard that biplane somewhere, so we know that the object was something else entirely. The object was never obscured by houses or trees at any point. It either disappeared, or was simply so fast it was hundreds of miles away in mere seconds. I am a very logical thinker, and I cannot imagine what, in my index of known objects, this was. Moments after, a commercial plane flew in from another direction. It was blinking and went behind the clouds. The UFO was, without a doubt, not an airplane.((NUFORC Note: Witness elects to remain semi-anonymous; provides no contact information. PD))
