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.

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

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

Blank radar screens. Broken air traffic equipment. Flights in an out of Newark Airport delayed or canceled. Is it safe to fly here?

Passengers traveling in and out of Newark at the end of the week shouldn't expect smooth sailing. Here's the latest at the New Jersey airport.

The blackout included losing radar for about 90 seconds at Newark Terminal Radar Approach Control at 3:55 a.m. local time, a source with knowledge of the incident tells CNN.

Newark Liberty International Airport suffered another brief air traffic control outage Friday morning, the FAA confirms.

One of the region's busiest ports has come under scrutiny since revelations that its tower has lost contact with several planes in recent months.

The city of Newark will install radar detection equipment at a downtown intersection later this year to boost traffic efficiency and safety.
