Should Newark Airport close until air traffic control upgrades are made? Experts and officials debate safety and the economic impact.

Over the past two weeks, several equipment outages at the Philadelphia-based air traffic control center that guides planes to and from Newark Liberty International Airport, have raised questions on just how safe it is to fly at one of the nation’s busiest airports.

Transportation Secretary Sean Duffy explained Wednesday that he recently changed his wife’s flight to avoid the embattled Newark Liberty International Airport — but not because of safety issues.

Moving air traffic controllers means retraining them on the quirks of a new facility, and the process can take years.

At times Monday evening, as few as three air traffic controllers per hour were lined up to monitor via radar the planes flying into and out of the airport, the Federal Aviation Administration said.

The Federal Aviation Administration is considering temporary flight reductions in and out of Newark Liberty International Airport, and it's launching a safety task force.

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.
