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.

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

We have to fix this, because what you see in Newark will happen in other places across the country,” a top federal official said.

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

Newark approach lost radar and comms with at least 16 commercial jets. Many circled in oval loops before landing elsewhere. A CNN data analysis reveals the ripple effects from the outage.
