Newark Airport is experiencing significant delays and cancellations due to an air traffic controller shortage exacerbated by rain, with over 56 delays and nearly 100 cancellations reported by 7 a.m. Tuesday. The situation follows an equipment failure last week that led to a temporary loss of communication between controllers and pilots, resulting in several controllers taking trauma leave. U.S. Transportation Secretary Sean Duffy plans to announce a comprehensive overhaul of the air traffic control system on Thursday, aiming to modernize infrastructure and improve staffing, while the FAA is working to mitigate current issues through better equipment reliability.
