Transportation Secretary Sean Duffy joins 'Squawk Box' to discuss the ongoing delays and air traffic control outages at Newark airport, the launch of a Newark airport emergency task force, whether it's safe to fly in the U.

NBC’s Kristen Welker grilled Sean Duffy on the repeated air traffic control outages at Newark Liberty Airport and the transportation secretary didn’t seem convinced that his agency has a handle on the ongoing crisis.

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

The regulator still uses some computer systems that rely on floppy disks and other outdated hardware, according to one air traffic control union leader.

Transportation Secretary Sean Duffy said he has a plan to upgrade old air traffic control tech but warned more flight disruptions could come first.

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

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.
