I can confirm (through official sources on the base) that those were just booms - not to worry.

From the Dayton Daily News:
There was a scare late Tuesday afternoon when two thunderous booms rocked the Dayton area and televised news reports erroneously suggested that the Dayton VA Center may have been hit by a terrorist attack. Air Force fighter jets were spotted in the skies around that time, and Wright-Patterson officials said they were investigating whether military aircraft caused sonic booms.
