Bright triangular object seen over major interstate highway near medium size city.I was driving home from work on I-40 west bound in light traffic. The weather was dry and warm. I was between the 39 and 38 mile marker, when I looked up and noticed a triangular shaped object which seemed to appear out of nowhere, and it darted off toward the direction of Asheville city.The object seemed to be solid looking and triangular in shape. It appeared to make no sound, tho it was hard to tell at highway speed. It did appear to emit a very bright, gold colored light as it appeared and darted away.
