Guesses from a sonic boom to tanerite to military training activities from nearby bases all came up short.

The Fort Bragg Public Affairs Office said Marines from Camp Lejeune have been on base conducting heavy artillery training in recent days. A representative speculated it's likely the boom was related but stopped just short of claiming full responsibility.
Deputies with the Johnston County Sheriffs Office responded to several calls from residents who heard the boom; however, nothing was found.
