Residents of Hawaii experienced panic on Saturday morning when an emergency management worker mistakenly sent out a false alarm warning residents about an incoming ballistic missile. The alert, which residents received to their cellphones, read, “Emergency Alert: Ballistic Missile Threat Inbound to Hawaii. Seek Immediate Shelter. This is Not a Drill.” It took 38 minutes for Hawaii to then inform residents that the alert was, in fact, a mistake. This is Hawaii Governor David Ige.

Gov. David Ige: “Today is a day that most of us will never forget, a day when many in our community thought that our worst nightmare might actually be happening, a day when many frantically tried to think about the things that they would do if a ballistic missile launch would happen.”

Meanwhile, on Tuesday, Japanese residents also received a false alert about an incoming ballistic missile. This alert was sent as a news alert by the national broadcaster NHK.
