For 38 minutes on January 13th, people in Hawaii thought that a ballistic missile was incoming. The test operator selected the wrong option in the system and caused statewide panic when the ominous message appeared on everyone's smartphones. The department had no way to automatically issue a correction on the erroneous message, which lead to the time gap between the notice and the correction. The person sending out the alert wasn't the one truly at fault here. Instead, the failure to adhere to user interface design best practices led to this situation.
