Hawaii missile false alarm due to badly designed user interface, reports say

Alert occurred after employer pressed button labelled 'missile alert', instead of the one next to it marked 'test missile alert'

A false alarm warning Hawaiians of an incoming ballistic missile on Saturday, was reportedly issued because of a "terribly designed" user interface.

The computer system that allows the Hawaiian Emergency Management Agency (HEMA) to send emergency alerts asks employees to select the type of alert that they are sending from a drop-down menu.
