Saw what we thought was an airplane off in the distance.

My wife and I saw something really weird last night while driving home in this rural area around 9:00 pm. After turning from westbound Clark Shaw rd to southbound on Sectionline rd, north of Home rd., there appeared to be an airplane south in the distance, although "flighting" much lower than normal, in my opinion. As we continued driving south, we realized during our approach this machine was remaining in place hovering about a thousand feet above. We discovered it was not moving as we slowed down while driving under it. We slowed down to a crawl to view this machine that had a very bright white light (aviation) underneath the center mass surrounded by red and green lights, but it had no noise. Its' size appeared to be about a size greater than a small private plane or helicopter, but why no noise? As we continued south, it abruptly disappeared from view - no remaining lights. We continued to drive slowly as an oncoming car slowed down too. I was perplexed whether it was a drone, why no noise? This area is also known to have many utility high power lines dissecting the countryside - wouldn't this be a navigation issue for this machine too? Plus it was much bigger than drones I have seen in my professional career - previously observed drones displayed at an international security conference, for convention attendees to view. Also observed a militarized drone assembly production at an international manufacturing facility, while there on business - these produced machines consumed a physical size footprint of a 20' X 20' room, in my opinion.
