The historic disruption began when contractor L3Harris installed at least one new router that flooded air traffic communication systems with rapid connection attempts. This technical failure destabilized operations across 17 of the nation's 22 en route air traffic centers and prompted the longest systemwide ground stop since September 11, 2001. Major domestic carriers saw up to 45 percent of their daily schedules eliminated as cancellations exceeded 14,500 over two days. Lawmakers and administration officials are now reviewing the operational failure while debating emergency federal funding packages to overhaul the network.
