More North America Alerts

The command responded to nine general aviation aircraft that violated FAA TFR airspace over Bedminster, New Jersey, over one weekend and reached a cumulative total of 15 unauthorized incursions near Bedminster by June 8.

All aircraft were safely escorted out of the area. The Continental U.S. NORAD Region also enforced an FAA VIP TFR over New York on June 8 and issued public advisories directing pilots to review Notices to Air Missions before every flight.

Official releases document F-16 intercepts near Keansburg, New Jersey, on June 6 at approximately 1:40 p.m. EDT, during which flares alerted the pilot before escort, and another intercept on June 8 at approximately 9:30 p.m. EDT near the same location.

A June 8 intercept near Bedminster at approximately 3:55 p.m. EDT, combined with four later violations that day, contributed to the 15-incursion total near Bedminster since June 6.

The command and 1st Air Force accounts reported more than 10 violations in the prior three days as of June 9, including seven on a single day.

A June 11 press release summarized the pattern and stated that most TFR violations remain preventable through thorough pref-light planning. The release covered activity for the month and noted more than a dozen violations without releasing additional individual intercept details.
