Security Camera Footage Shows Supersonic UFO Over Arizona

• When: July 31st, 2017
• Where: Chino Valley, Arizona
• What: Large black craft moving at extreme speed

8/8/2017 Update: I've now confirmed that the person who uploaded the YouTube video of this sighting is also the witness. They followed up with me and the following comment to share: "We did not see this with our naked eye, but there were three of us in the room at this office reviewing the video on the DVR when we saw the object. We'd like to hear from anyone else in the area that saw it as well. "

Original report:
Security camera footage showing a large, elongated black craft descending at an extremely high rate  of speed over Arizona has been submitted to MUFON (case 85677) and then re-shared on YouTube. The witness noticed the UFO when viewing the security camera footage; they didn't recall hearing the craft fly over, but did hear a man talk about seeing something that he couldn't explain the day before:

This was video from a security surveillance system in Chino Valley, AZ, USA. We were watching it for another reason, when we noticed a strange object fly across the sky at an amazing speed.

The view is to the North-Northwest and the object appears to fly in a straight line from the Southeast to the Northwest. It appears above the eve of the building, travels into and behind the clouds, then reappears for a moment before going behind the trees.

We were in the building at the time and did not hear anything. one person I spoke with said that he heard a story about something he couldn't explain in the sky, "the other day", but I was unable to speak with the person personally. Any thoughts are welcome.

If you have seen something like this before, please report your sighting and help crack this case!

Do you have theories on what this UFO could be? Perhaps it is just a simple yet? Or could it be something a bit more intimidating, like a missile (as the YouTuber  who re-shared the video sensationally suggests) or an advanced top-secret military, or alien, craft?
