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.

Radar screens at New Jersey's Newark Liberty International Airport went black again early Friday morning. The outage happened at 3:55 a.m. and lasted about 90 seconds, the Federal Aviation Administration said.

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

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?

Newark Liberty International Airport in New Jersey has been dealing with nonstop delays and flight cancellations due to outdated equipment and air traffic control understaffing across the U.S.

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

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