"Control tower cannot see the plane"? Newark Airport chaos exposes fatal flaws in American aviation system.

The Federal Aviation Administration (FAA) of the United States announced on the 9th that there was once again a malfunction on the radar screen at Newark Airport in New Jersey. According to American media reports on the same day, due to construction issues at Newark Airport, the FAA issued a ground stop order until 11:15 a.m. Since April 28, chaos, including a large number of flight delays, has continued to occur at Newark Liberty International Airport, one of the busiest airports in the United States. According to reports, more than 1000 flights have been canceled. The reason behind this? CBS News reported that the Philadelphia Terminal Radar Approach Control (TRACON) responsible for controlling airspace at Newark Airport has faced long-term personnel shortages, reducing its ability to provide approach control services for arriving, departing, or transiting aircraft.
