A significant outage of FAA equipment has caused widespread flight disruptions across major Northeast airports, including Newark, Philadelphia, JFK, and LaGuardia. Ground stops have been implemented, resulting in hundreds of flights being delayed or grounded. The outage has been linked to a fiber cut by construction workers, leading to communication failures in air traffic control systems. Travelers at affected airports are experiencing extended delays, with some ground stops exceeding six hours. As emergency measures are taken and communication systems are restored, some flights have begun to resume; however, the situation remains chaotic with ongoing issues reported throughout the region.
