The long flight delays and cancellations plaguing Newark's Liberty International Airport and spilling over to airports across the U.S. can be traced to a week ago when air traffic controllers temporarily lost communications with planes in the sky, according to the controllers union.
Crews in the Philadelphia air traffic control facility that lines up flights going in out and of Newark lost radar and communications with the planes on April 28, according to the National Air Traffic Controllers Association. The outage left controllers “unable to see, hear, or talk to” planes under their control, union spokesperson Galen Munroe said.
