Fire in the hole! 

An explosives team detonated a Civil War-era cannonball yesterday afternoon at Joint Base McGuire-Dix-Lakehurst, resulting in a boom that was heard and felt in portions of Ocean County.

In addition to the 12-pound cannonball, the 87th Explosive Ordnance Disposal team detonated a mortar and small hand grenades that were all found in Bergen County, NJ.com reported. 

A military spokesperson posted on the base's Facebook page that the overcast conditions could result in the sound traveling farther or seeming louder. 

That was confirmed by social media comments.

"Heard that thing go off. I think it scared every goose in Ocean County cause they all headed east over my house very quickly afterwards," Tim McCarthy wrote on the base's Facebook page.
