GREEN BAY (NBC 26) — While flights continue to take off and land normally, federal workers essential to airport operations are working without paychecks. This includes TSA agents, air traffic controllers, and customs officers who keep air travel moving safely. Traveler experiences at Austin Straubel have been mixed. Marty Piette, airport director for Austin Straubel International Airport, emphasized that essential services remain operational. The shutdown's impact extends beyond air travel, potentially affecting federal grants, small business loans, and even National Guard operations throughout Wisconsin.
