“Air-traffic controllers in other West Coast areas similarly ordered aircraft down, according to recordings shared online.”
Why would "Ground Stop" be ordered but limited to West Coast airports if an EMP was truly expected?
A half-azz Yung Fat mid-height EMP over the Sea of Japan or even the other side of Japan would maybe be a regional theater operation with the locus Japan + 2500mi radius, so it would encompass South Korea, Philipines, and Taiwan.
Not one of them called for "Ground Stop".
This smells like a pre-programmed scenario to reveal to the CCP how Xiden'a West Coast civilan ATC would react to a 'rogue' EMP release by the North Koreans PLA.
