I live in the country and i was outside in my yard when i saw them coming from the se. there were aircraft flying about 30,000 ft up in the night sky but none in the immediate vicinity of these objects. the aircraft have blinking red and white lights. these objects had blinking white lights and were circular shaped golfballs. they were flying in a triangle formation but they were not in a stationary formation. they were high above the treetops but low to the ground and they made no sounds as they passed over my pasture.
