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.

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.

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

A technical outage in Philadelphia last week terrified air traffic controllers and stranded passengers. As the summer travel season looms, the F.A.A. is racing to address the problems.

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