I’m with the reporter - with the additional mil flights and activity I could easily see this as a sonic boom and that is interesting in itself as military doesn’t normally do that close to civilian areas - not only due to noise complaints but also possible damage.
If military went supersonic close to civilians there is either a hot dog or a definite reason.
The last incident I recall hearing about where jets went supersonic over a populated area was on 9/11 when the Ohio Air Guard took off from near Toledo and were headed east towards Flight 93. My mother heard and saw 2 jets while she was out golfing near the Cleveland/Akron area.
They may have gone supersonic around here a few times also, but at very high altitude. I'd hear the boom, run outside, and spot a plane way up there, probably above 40,000 feet. That was in SE Tennessee, and I believe they were testing the F-35 at the time.
