Newark Airport has faced a number of air traffic control equipment outages in recent weeks.

Nearly 80 flights have been cancelled and more than 40 delayed at Newark Liberty International Airport after yet another an equipment outage brought more chaos to the NYC-area hub.

The latest incident highlights the air-traffic-control network's aging infrastructure and comes a day after Transportation Secretary Sean Duffy proposed spending billions of dollars to fix it over the next three to four years.

Several times over the last year, Newark controllers lost radar or radio service, leaving them unable to talk with planes they were tracking.

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

Similar to last summer, there is currently a nationwide shortage of air traffic controllers, which will “take time” to replenish, according to Transportation Secretary Sean Duffy.

Caught in the middle of the issues at Newark is United Airlines, which is the most active airline at the New Jersey airport. While the problems lie with the FAA system, the airline is where people often aim their frustrations over cancellations and delays.
