The Federal Aviation Administration (FAA) issued a rare nationwide ground stop on Friday, halting all domestic flights due to a major communications failure. The shutdown, attributed to 'extraordinary circumstances for safety reasons,' left numerous travelers stranded, including model Brooks Nader.

Nader was reportedly on the tarmac in New York City, preparing to depart on a private jet to attend an LSU football game in Louisiana. Sources told TMZ that Nader was safe but that pilots had not received updates on the situation, leaving uncertainty about her departure.

Nader had shared a selfie from what appeared to be a private jet on her Instagram stories, indicating she expected to travel the following day and mentioning an appearance at a Fred's Bar and Bumble takeover at the LSU game. However, the FAA's order disrupted these plans.

The Air Traffic Control System Command Center (ATCSCC) announced the halt at 3:54 p.m. ET, citing a "temporary telecommunications outage." The agency stated that all flights were accounted for and that international flights would be handled on a case-by-case basis. While preliminary reports suggested the outage was not a cyberattack, the FBI was monitoring the situation, according to a law enforcement source who spoke with CNN. Department of Homeland Security Secretary Markwayne Mullin also stated there were no signs of foul play.

The Associated Press reported that the incident did not appear to be linked to the FAA's new AI-powered system, which is being implemented to help predict issues in the air.

Other notable figures also experienced disruptions. Bachelor alum Kaitlyn Bristowe shared her distress on Instagram stories, describing the situation as "eerie" and "spooky," especially given it was Friday the 13th. Fitness influencer Jen Selter was reportedly in the air when flights were grounded and later posted from an airport terminal.

Approximately 600 flights were diverted as a result of the FAA's order. Europe subsequently suspended all U.S.-bound flights, and cargo flights also faced delays.
