Hawaiian Missile Threat Mishap

After investigation it has been deemed a result of human error, in part due to badly designed user interface, whereupon an employee at the Hawaiian Emergency Management Agency (HEMA) inadvertently pressed \"Missile Alert\" instead of \"Test Missile alert\"

According to a report in the Guardian \"In the days since the alert, HEMA has made a number of tweaks to the computer system to prevent a repeat of the error. It has added a “cancellation button”, allowing users to send a second alert over the same system that notifies recipients that the first was a false alarm. On Saturday, sending that second “false alarm” alert required extraordinary permission, delaying it for 38 minutes. HEMA has also added a requirement for a second person to confirm the message to be sent, hopefully preventing the first from simply clicking through mistakenly\".
