Triangular craft with lighted sphere bottom hoovering near home in cumming, ga 7-28-10My son was home playing on his xbox with a group of other online kids, when he heard what he described as the sound of a plane landing. He took off his headset, stopped playing the game and went outside to see what he thought might be a military helicopter. (we do see military helicopters fly over our home ). He told me he saw a large dark colored triangular shaped craft that had a sphere shaped lighted thing underneath. He also stated he could see "windows' on both sides of the craft, but that they were gray "tinted" looking. The sphere had a yellow-whitish light that pulsated. The craft hoovered over the back field directly in our back yard. Then the craft shot off very fast into the clouds and disappeared. I asked him if he was afraid while he stood outside and looked. He told me that he didnt believe in UFO's, but while he was looking at it he did become confused and somewhat afraid.
