A mysterious boom baffles Tampa Bay, and official sources shrug...

Was one in my town a few days ago. Nobosy knows whar it was.

Thats stony plain - Alberta

It was the cast of Floribama Shore.

Nothing to see here folks, just idiots getting riggity-wrekt.

It appears it was a pair of F-15s going supersonic in a training area.

Indeed

"The loud noise reported Saturday afternoon in the vicinity of Tampa was more than likely the result of a sonic boom caused when two F-15 fighters from the 159th Fighter Wing based in New Orleans and operating under the direction of North American Aerospace Defense Command went supersonic to meet mission requirements,” said USAF Captain Chase McFarland.

The 159th Fighter Wing is a unit of the Louisiana Air National Guard. It generally trains over the Gulf of Mexico.
