Two F-16 fighter jets were dispatched by the North American Aerospace Defense Command to intercept a civilian aircraft near Washington, D.C., NORAD said Wednesday.

The incident happened about 12:15 p.m. ET after the aircraft failed to establish radio contact, the agency said in a press release.

“The civilian aircraft re-established communications and was allowed to continue on its way without incident,” NORAD said.

Out of an abundance of caution, officials are being vigilant about security concerns around the holidays.

After the 10-year anniversary of 9/11 in September, two fighter jets were scrambled after reports of air passengers acting suspiciously on two flights. Although no problems occurred, authorities sent F-16s to shadow the flights just in case.
