Data from Flightradar24 showed what appeared to be dozens of planes at the airport with none taking off.
Transportation Secretary Sean Duffy said the ultra-rare “nationwide ground stop” was ordered because of a “communication issue impacting all Air Route Traffic Control Centers.”
“FAA technicians are investigating the issue. We will provide immediate updates as we have them,” he added.
