Transportation Secretary Sean Duffy says a new software update prevented a third radar outage over the last two weeks at New Jersey's busy Newark airport when a telecommunications line failed again over the weekend.

At times Monday evening, as few as three air traffic controllers per hour were lined up to monitor via radar the planes flying into and out of the airport, the Federal Aviation Administration said.

The failure was the second such incident in the past two weeks, amid continuing concerns over safety at the airport.

The air traffic controllers directing planes into the Newark, New Jersey, airport lost their radar Friday morning for the second time in two weeks.

A brief radar outage occurred at Newark Liberty International Airport early Friday morning, lasting approximately 90 seconds. This incident follows similar outages in April and November, raising concerns about the reliability of air traffic control systems ...

Transportation Secretary Sean Duffy plans to reduce the number of flights in and out of Newark Liberty International Airport for the "next several weeks."

The FAA was set to have a “delay reduction” meeting Wednesday, seeking to cap the total number of flights at the airport.

Staff shortages and equipment failures at Newark Liberty International Airport have raised safety concerns in recent weeks.
