On Saturday, people in Hawaii got a pretty big scare when they received an emergency alert warning them of an incoming ballistic missile.
It turned out to be a false alarm. Officials say a Hawaii Emergency Management Agency employee accidentally pushed the wrong button.
The agency says it does internal tests at every shift change and that the employee sent the alert — even clicking through a safeguard meant to prevent such a thing.
If there's a silver lining here, it's that officials say they're already improving the system. They say they'll require two-factor identification for sending alerts in the future and that they're reviewing some glitches they noticed in the alert system.
