The user was to select from a menu of options including “Missile Alert” and “Test Missile Alert”, which were next to each other on the options menu.
The system also lacked a “Cancel missile alert” feature so no one knew how to un-do the transmission of the fake missile alert.
As I suspected, the system design was so bad, they never thought to add a “cancel alert” feature to the system. Other news reports say no one will lose their job over this or be reprimanded. This sounds like an organizational leadership and organizational culture failure – bad design, bad implementation, bad procedures, lack of leadership.
