Transportation secretary unveiling plan to overhaul air traffic control system after Newark airport outage

Transportation Secretary Sean Duffy is expected to unveil his plan for a new air traffic control system Thursday. The announcement comes as the international airport in Newark, New Jersey, continues to deal with disruptions following an outage last week.

Air traffic controllers directing flights into Newark Liberty International Airport lost communications and their screens went blank for about 90 seconds on April 28.

"We don't have a radar, so I don't know where you are," one controller was heard saying on a recorded transmission.
