Standing in front yard. 1 large triangle shaped dark black aircraft with red lights on all corners flew/floated a very low, about 200 feet over top of me. It was very quiet but there was a very slight whooshing/welling sound to it as it passed over it was very big, it blocked the stars. As it flew rewords the west, 2 other aircraft came from the west and all 3 met over top of a mountain ridge and headed north up the ridge along the River. The aircraft that flew over top of me was in the lead.
