Sitting at my office desk looking out the back door window, which is next to desk, noticed red/orange fireballs (looked like a kettle fire) flying at a constant speed towards my home at about 600 to 800 ft. high at about 100 mph. I went outside looked more closely, noticed there were two flying horizontal to the ground making no sound and slowing to a halt in the sky, meeting with two others that were already waiting. Then I went out onto my driveway (in front of my home for a better view) with my wife and son and observed them as two more approached and hovered in formation with the other four that I could see through the tree tops. They were turning down the flame that Formed a “V” shape, flaming up from the bottom of the craft going upwards covering the craft while hovering, no sound, until they disappeared against the clear night sky. This all happened in about 8 to 10 minutes at about 7:30 PM. I live at the edge of the forest and have seen them many times landing in the woods or flying over. Since 2010, counting this sighting, it makes 9 sightings. One of these was of the third kind, seeing the sphere land and its occupant with witness. All but two sightings, I had a witness.
