U.S. officials blamed overloaded and outdated systems for the nationwide flight ground stop, saying there is no indication a cyberattack caused the FAA communications failure, according to AP. The disruption halted flights across the country, though the report did not specify the number of flights or passengers affected. The explanation points to infrastructure capacity limits rather than malicious activity as the root cause. Attention now turns to whether regulators will fund upgrades to the FAA's aging communications systems to prevent a repeat outage.
