FAA ends four-hour nationwide ground stop after communications outage
The Federal Aviation Administration ended a four-hour nationwide ground stop on 13 November, allowing departures to resume across the United States after a telecommunications, radar and transponder failure disrupted air-traffic control, the Guardian reported. Earlier that day the agency had ordered all flights to remain on the ground because of the outage, the first nationwide shutdown since 2001, affecting tens of thousands of passengers, Reuters reported. Officials said the problem was technical and found no evidence of a malicious attack.
