UFO Flyby Captured on Video Recording

Occurred on May 20, 2018 / Post Falls, Idaho, USA

Info from Licensor: "We had spent all day looking for a new car for my fiance. I started recording her driving past us, so she can see how nice the car looked. I replayed the video after recording an thought i heard something. I replayed it again and saw that something flew past real fast! What blew my mind even more is that I saw nothing fly by or hear anything fly by when I recorded the video. Eventually, I slowed it down, took screen shots and just was clueless. All I can think of was 'Could this be a UFO?' Jets are to loud and drones have a nice loud buzz sound and I heard nothing pass by."
