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

The CEO of United Airlines maintains that New Jersey's Newark Airport is safe, despite construction, equipment failures and staffing issues that have resulted in delayed and canceled flights, NBC News' Marquise Francis reports.

Transportation Secretary Sean Duffy keeps going on TV and insisting it’s safe to fly in and out of Newark Liberty Airport in New Jersey, despite a string of extremely frightening outages and workforce shortages recently. But Duffy has now admitted he changed a flight booked for his wife on Monday so that she wouldn’t have to travel through Newark.

Marquette-Sawyer Airport Rescue Firefighters Chief Joe Perry says teams practiced putting out propane fires, creating a rescue path and searching for survivors in a smoke-filled plane. He says drills like this one are crucial, as fuel fires are different than structure fires and must be combated differently as well.

Yemen's Sanaa International Airport will resume operations from Wednesday, the airport's general director said on Tuesday.

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

Transportation Secretary Sean Duffy said Monday that “fast-track” fixes are being made to address the continuing communications and radar failures at Newark Liberty International 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.

It has been a scary few months for air travel. Faltering technology in the air traffic control hub that watches over Newark Liberty International Airport has caused the radar system to fail at least twice in recent weeks. Airplanes have bumped wings in San Francisco and Washington, D.C.
