The US Federal Aviation Administration has lifted the longest nationwide ground stop of flights since the 11 September 2001 terrorist attacks.
The FAA said Friday's stoppage, which lasted more than four hours, was "due to extraordinary circumstances" from a communication issue affecting all air traffic control centres.
Homeland Security Secretary Markwayne Mullin said there was no indication of an attack and that everybody was safe.
