Video shows inside of Philadelphia air traffic control facility that handles Newark flights during outage last week

An exclusive video obtained by CBS News shows inside the problem-plagued air traffic control facility that handles flights in and out of Newark Liberty International Airport during the brief outage that occurred on May 9. 

The video shows inside area C of the Philadelphia Terminal Radar Approach Control, or TRACON, with blank screens, and air traffic controllers can be heard talking. The video also shows the system coming back on. 

The brief 90-second outage occurred at 3:56 a.m. Eastern Time on May 9, an especially slow time of day when very few flights were in the air. Other areas of air traffic control were still able to monitor any aircraft the Philadelphia facility was handling during the outage.
