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 airport air traffic controllers lost radar Friday morning for 90 seconds. The FAA announced that it plans to install new fiber optic data lines to carry the radar signal between its facilities in Philadelphia and New York. NEW JERSEY - Newark airport is not out of the woods yet.

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Liberty International Airport in New Jersey has been dealing with nonstop delays and flight cancellations due to outdated equipment and air traffic control understaffing across the U.S.

Air traffic controllers guiding planes into Newark faced equipment outages for the second time in a month early Friday, the FAA said.

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

Sen. Andy Kim, a New Jersey Democrat, said the FAA is not being transparent enough after visiting air traffic controllers in Philadelphia and Newark.
