At about 10:00 in the morning, my friend and I were traveling North on US395, from Susanville, California, at about 75 M.P.H., heading toward Alturas, California when in the distance a shiny silver metallic object,(reflection from the sun), crossed over the highway, about a half mile North of our location. At first I thought it was a low flying crop duster type of airplane, because it is an agricultural area, but then the object made a sharp 90 degree turn, and headed toward our location, but to our left . The object traveled in a straight direct path, at approximately 60 M.P.H., and came to a instantaneous dead stop in the air. The object was about 40 feet off of the ground, about 500 feet off of the Highway on our left. I stopped and parked the car, and left it idling, and after about 1 minute, my friend and I got out of the car, and stood on the highway to observe the object. The object was a Doubled or 2 attached Sterling Silver colored Spheres, and it was stationary in the air, about 40 feet off of the ground. It made no noise at all. I can judge the approximate size of the object because of its approximately to a wood T-shaped telephone pole. My estimation is that it was about 40 feet high X 80 feet long. My friend and I observed the object for about 4 minutes, outside of the car, when we noticed a silver shark fin shaped member emerge from the upper forward side of the object. My friend was becoming increasingly agitated, nervous and afraid, and was insisting that we leave immediately. So, I agreed, and we hurriedly jumped back into the car, and I sped away at about 120 M.P.H. toward Alturas, California.(note: the photo is similar to what we observed, but doubled and attached)
