All these shills saying it's animals or what have you, are LYING. If it were anything like an owl (or even a release valve), why would there be videos -- miles apart, mind you -- witness to the same exact sound? And why was this also reported in California by multiple witnesses at 1:30 am on May 27? And why would all these residents be bewildered about it, if it were something as simple as an animal or release valve? Logic says they would have heard that sound before. This is no human-created phenomena. Beware the DoD's shills on GLP. They're basically blue checkmarks on Twitter.
