Sean Duffy said it is safe to fly, but major outages such as the ones in Newark could still pose “a risk to life” and must be swiftly resolved.

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

Similar to last summer, there is currently a nationwide shortage of air traffic controllers, which will “take time” to replenish, according to Transportation Secretary Sean Duffy.

The recent chronic delays and cancellations at New Jersey’s largest airport have highlighted the shortage of air traffic controllers and the aging equipment they use, which President Donald Trump's administration wants to replace.

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

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.

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.
