Observed red lights through the trees coming up the river from a southerly direction heading north. my seven yr. old saw it first, and asked if it was a car. i turned and looked at the road, and he said, "no, up there". we all turned and looked up and saw the object through the trees. object made no sound. object appeared to be rectangular. would light up all red light, then totally black, light up all red, then totally black. object came into our full view after passing trees in front of us. object was approx. 150-200 ft. above the water, maybe more. we had a clear view of the object for at least 5 minutes. object was observed by two adults aged 50 and 48, and 3 children aged 7 and 10. we had plenty of time to observe and rule out what we knew it wasn't, it was no plane, propeller or jet. it was not a helicopter. there was no sound at all. just all red to black. i would guess object was maybe 50 ft. or so, hard to say. the only way i came up with that size is by comparing it to boats i see on the river. i would guess it was maybe 200 ft. above the water, our house is on a hill above the water, so the object was very clear and only a little above us. it was about 200 yards away in the air. it went straight, came level with us and slowly turned to it's right and went in an easterly direction and just went that way until it went out of our view. made no sound, i cannot guess it's speed, but way too slow for a plane.
