Honolulu’s 911 dispatchers were inundated with more than 5,000 calls immediately after an emergency cellphone alert warned that a ballistic missile was headed for Hawaii.
The thousands of calls overwhelmed the city's 911 system, the mayor said, and approximately half went unanswered, Honolulu Police Chief Susan Ballard told NBC affiliate KHNL. The city's police, learning early on that it was a false alarm, sent officers out with bullhorns to calm neighborhoods, she added.
Welcome to 1941.

One of the first lessons from the terrifying incident, experts say, was that calling 911 is not the best first-response to an imminent nuclear disaster. In the larger sense, the false alarm served as exactly what it said it was not — a drill.
