Audio between air traffic controllers and pilots at Newark Airport reveals the moment the tower lost radio contact with planes.

The union representing Air Traffic Controllers released new details about technology failures that disrupted flights at Newark's airport.

At least five air traffic controllers have taken 45-day trauma leave, per CNN, suggesting delays at Newark, which averaged two-hours-and-forty minutes on Monday, will endure for some time. Any delays will be exacerbated by the renovation to one of Newark’s runways, which will continue until June 15.
