The safety nightmare continues at Newark Liberty International Airport, where all air traffic control will be manned by just one fully qualified person during its busiest time tonight, The Post can exclusively reveal.

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.

Caught in the middle of the issues at Newark is United Airlines, which is the most active airline at the New Jersey airport. While the problems lie with the FAA system, the airline is where people often aim their frustrations over cancellations and delays.

Much has been made over the recent air traffic control system failures at Newark Airport, but in reality, the problem goes back a long time. According to a new report from CNN, air traffic controllers "repeatedly" warned of major safety issues and technology outages as early as last summer,

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.
