The Federal Aviation Administration (FAA) is facing significant challenges due to outdated technology and staffing shortages, prompting the agency to buy replacement parts on eBay and utilize 3D printing for repairs, according to Transportation Secretary Sean Duffy. At a Senate hearing, Duffy emphasized the urgent need for a comprehensive overhaul of the air traffic control system, which could cost billions, while acknowledging that safety is currently maintained through redundancies despite criticisms regarding recent staff cuts. Lawmakers expressed concern over the implications of these cuts on safety, especially following a series of alarming incidents in U.S. air travel.
