Transportation Secretary Sean Duffy's announcement comes as Newark Liberty International Airport continues to deal with disruptions following an outage last week.

An experienced air traffic controller retired just days after his radar failed as planes flew into New York airspace, according to The New York Times. The fault meant the Philadelphia-based Newark Liberty International Airport controller lost radar imagery for around a minute and a half on Aug.

A deadly midair collision in January between a military helicopter and a commercial airliner, and several crashes since, have prompted officials to focus on fixing the nation’s outdated air traffic control system and hiring more controllers.
