Large sphere shaped light. The sphere was the light source.((ADDENDUM FROM WITNESS))The siting was at a Copper Mine, 120 km from Houston BC. I had just stopped for my last coffee. The night was bright because of the moon overhead. High, thin clouds. I saw a haul truck cresting the hill with its headlights on. Behind and above that haul truck was what looked like a very large light falling from the sky. It was a sphere in shape and very bright. It was falling at about a 45 degree angle. I was thinking there was gonna be a loud crash. Maybe this was a plane or something. It was only a short distance from the ground, maybe 100 feet. It disappeared behind a large stockpile. The light object was about the size of two haul trucks. There were four other people who saw this from all sides. The object passed over a large roadway we call tmf2. Crossed a water area and went just over the hill. There it disappeared. No crash, no fire, just disappeared. It was a solid light with no tail or anything following it and no noise of any kind. If you have any idea what it was, please let me know. I am so sure of what I saw as well as confirmation from the other eye witnesses.
