High Altitude Bright Light during mid-dayI was traveling north by car on State Route 2 just south of the town of New Cumberland, when I saw a light in the northern sky. The time was 2:23pm (local eastern) and the sky was clear and sunny. The light appeared to me to be an airliner at first. Upon further review, the altitude must have been 100,000+ feet and the distance from my location unknown. The light did not move in the sky. The intensity of the light is really what kept my attention; it was as bright as the sun. I did pull my car to the side of the road to watch it because the size vs. altitude was not adding up in my head to be correct. After about 1 minute, the object turned black/dark grey and seconds later I was unable to locate the object with my eyes. Even when it turned black/dark grey, the size to altitude ratio would have made the object much bigger than an airliner.
