Saturday, June 17, 2017, 22:30 hours St. Charles / St. Peters Missouri I live approximately 2 miles south of Interstate Highway 70, and about 3 miles west of the Missouri River.At 10:30 pm this evening I went outside in my back yard to secure the patio furniture for incoming storms that were predicted. The rear of my house faces due north. I looked up into the sky and saw lightning far off in the distance towards the north. I then noticed two red balls of light traveling from the west (approximately along the path of I-70) moving to the east at a fairly rapid speed.At first I thought it might be a helicopter, or two. As they came closer, I heard no sound from any type of engine. Two lights travelling the same distance apart in the same path. Red orange in color, not blinking, but solid the entire time.As they came from the west, about the time they were directly behind my home, the lead light turned due north and appeared to gain altitude, fading from view, possibly behind clouds. The second light followed the exact same path as the first one, and also disappeared.About two to three minutes later, from the south west of my home, and closer to my home, I saw three additional lights, the exact same appearance as the first two. The first two were closer together, with the third one trailing a bit behind. I called my wife out to see what I was seeing, and to bring her cell phone to take pictures. She arrived, and confirmed that she was seeing what I was seeing. She tried to take pictures, but they did not turn out very well.Again, the three objects followed the same path of the first two, and turned due north, fading away from my view. No sound of any engine was ever heard, no other color of light was ever seen other than the red/orange solid light color.At first I thought it might be a Japanese lantern display of some kind, but the objects were moving too fast, and the winds were from the northeast, the opposite direction that the objects were moving. The two separate groups maintained a distinct separation distance from each other, and equal speed. Hot air Japanese lanterns would not behave this way.Aircraft routinely fly over our home as they move into the landing pattern for St. Louis Int. Airport Lambert Field. I know what an aircraft looks and sounds like, and how it behaves. I do not believe these objects to have been aircraft.I am not a believer in aliens, or UFO’s. I like to believe that there is a logical explanation for what my wife and I both clearly saw in the sky this evening. See attached jpg map of the flight path of these objects
