U.S. officials have attributed the November 13, 2026, nationwide FAA ground stop to overloaded legacy telecommunications equipment and aging infrastructure in air traffic control centers, with Transportation Secretary Sean Duffy citing inconsistent radar and communications data from outdated routers. Homeland Security Secretary Markwayne Mullin stated there was zero evidence of a cyberattack or malicious activity, describing the issue as mechanically driven rather than nefarious. These primary-source statements from the Trump administration, combined with the absence of any foreign actor claims or supporting indicators, underpin trader consensus that the outage will not be attributed to Iran. Further investigation could still shift outcomes if new technical forensics reveal external interference, though current data shows no such links.
