The ground shook and windows rattled in South Jersey this morning, and it remained a mystery for a while—especially after local Air Force personnel said they weren't to blame, reports the Examiner. But officials later confirmed that military aircraft had shaken up the state with a sonic boom, the Star-Ledger reports. Those officials are calling it a "non-incident" unworthy of investigation, but residents say they were shaken up.
"My basement door shook violently for 15 sec or so long enough to creep me out," one person posted on the New Jersey Shore Hurricane News Facebook Page. "Sounded like someone was trying to get out." Another called it "a huge explosion. ... I have never heard a sound like that in my life."
