Lost radar and silent radios have significantly disrupted air travel at Newark Airport, drawing attention to broader issues within the U.S. aviation system. Questions surrounding the causes and solutions for these disruptions remain unanswered, with some attributing the problems to outdated infrastructure. While President Trump proposes costly fixes to address the nation’s aviation challenges, these plans already face significant opposition. The Federal Aviation Administration (FAA) is currently working to resolve immediate issues at Newark while planning a broader overhaul of the U.S. air traffic control system. Pilots and industry experts warn that Newark’s problems could be indicative of larger systemic risks across the aviation sector. — new from The New York Times
