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

Recent communications issues at the FAA facility handling flights in and out of Newark airport were not new, officials say. Outages happened at least three times last year. CBS News senior transportation correspondent Kris Van Cleave has more.

The FAA is holding a “delay reduction” meeting Wednesday, seeking to cap the total number of flights at the airport.

Technology and staffing problems have plagued the airport, one of the nation’s busiest hubs. Officials say they are trying to resolve the issues, but concerns remain.

Newark Liberty International Airport is facing another FAA-imposed ground delay due to staffing shortages, after a telecommunications issue led to delays on Sunday.

Transportation Secretary Sean Duffy released a four-point plan to address the failing infrastructure at Newark Liberty Airport.

CHICAGO (Reuters) -United Airlines is facing a financial hit and potential long-term reputational harm as flight delays and cancellations pile up due to ongoing disruptions at Newark airport - one of its largest hubs and among the busiest in the country.

The shortage on Monday forced the F.A.A. to delay flights to the busy airport for up to nearly seven hours, the latest problem to plague the airport.

But our air safety system is faltering on more than one front. In late April, the Newark airport — one of the busiest in the country — experienced a radio and radar outage for about 90 seconds. With pilots dependent on air traffic controllers to navigate the busy airspace near airports, seconds of silence could be fatal.
