Duffy said during Monday’s press conference. “In July of 2024, the Biden [and] Buttigieg FAA moved control of the New York Newark airspace from New York [N90] to the Philadelphia Tower [Philadelphia TRACON].”

He said that as part of the move, the Standard Terminal Automation Replacement System (STARS) system which processes radar data for Newark stayed based in New York. Telecommunication lines would feed this data from New York to Philadelphia TRACON, where controllers would then handle New York arrivals and departures.

“The Biden [and] Buttigieg FAA bungled this move without properly hardening the telecom lines feeding the data which was already well known to be error-prone,” he said. “Without addressing the underlying infrastructure, they added more risk to the system.”
