Flights resumed across the United States on Friday after a nationwide suspension lasting more than four hours due to a communication failure at air traffic control centres.
According to CNN, the Federal Aviation Administration (FAA) ordered all flights to be grounded at airports across the country around 4 PM local time following disruptions to the control centres' communication systems.
The FAA lifted the suspension at 8:15 PM, allowing flight operations to return to normal.
