Travelers face disruption as some US flights resume after nationwide ground stop | CNN

• Travel misery: Thousands of travelers face an uncertain weekend at airports across the country because of delays amid yesterday’s nationwide hours-long ground stop forced by a telecommunications outage. Some domestic US flights are now resuming but airlines face a battle to clear the backlog.

• Possible cause: The Trump administration has blamed old air traffic control technology and overloaded routers, pointing to FAA updates to those aging systems. The ground stop did not stem from a threat to the US and was not linked to this week’s disruptive Microsoft outage, Homeland Security Secretary Markwayne Mullan said.
