Air traffic controllers handling flights approaching and departing Newark Liberty International Airport experienced another outage early Friday morning.
The blackout included losing radar for about 90 seconds at Newark Terminal Radar Approach Control at 3:55 a.m. local time, a source with knowledge of the incident tells CNN.
A separate source adds that the facility also lost radio communications.
It’s the latest in a series of troubling technical problems that have impacted the air traffic control system in the United States.
On April 28, an outage of radar and communications at the same facility left controllers unable to talk to planes or see where they were located. As CNN previously reported, at least five controllers took 45 days of trauma leave after that incident, leading to a staffing shortage that canceled and delayed more than a thousand flights.
