I am laying on my back in the grass talking to my mom and our co-workers and I noticed a large triangular object gliding slowly in the air. I kid you not, not a freaking sound was coming from this object. I alarm my mom and the other two to look up. We watch this triangular object coast..it was massive. Very large with red circular lights at the corner of each point. We hear no sound what so ever, not even a cricket as we do normally. This thing was so huge it began to block out the light from the moon and it got real dark for the entire ten minutes left on our break. As we stayed out to watch this thing, it continued to coast in the sky. I am not good with measurments and can't exactly tell you how high up it was, but I know it wasn't to high becuase it blocked out the moonlight for ten freaking minutes but high enough not to see any details on the object. It glided real, real slow and I swear to you guys that this happened.
