An unusual ground stop was issued to some pilots for a short period of time following a North American Aerospace Defense Command alert of a launch of a North Korean missile, a US official said Tuesday.
The official says it was not a national ground stop and may have been issued by a regional air traffic control facility."No warning was issued by NORAD HQ," regarding a potential threat to the US, according to Captain Pamela Kunze, the chief NORAD spokesperson.
The Federal Aviation Administration, responsible for the nation's air traffic control system, and NORAD have not responded to CNN's multiple requests for comment on why some pilots were ordered to land and prevented from taking off from multiple West Coast airports on Monday afternoon, citing a "national ground stop."
