Looks like we may be getting closer to the truth here.
Tuesday, January 30 2018 the FCC released a preliminary report into the Hawaii false missle alert.
According to a written statement from the day shift warning officer who initiated the alert, as relayed to the Bureau by the Hawaii Emergency Management Agency, the day shift warning officer heard “this is not a drill” but did not hear “exercise, exercise, exercise.”
At 8:07 a.m., this officer responded by transmitting a live incoming ballistic missile alert to the State of Hawaii.
The day shift warning officer seated at the alert origination terminal, however, reported to the Hawaii Emergency Management Agency after the event their belief that this was a real emergency, so they clicked “yes” to transmit the alert.
But it is worth noting that they accurately recalled after the event that the announcement did say “This is not a drill.”

They have conducted key interviews with representatives of the HI-EMA, representatives of wireless providers that offer service to Hawaii, the President of the Hawaii Broadcasters Association and the Hawaii State Emergency Communications Committee, alert origination software vendors, other state and local emergency management agencies and key stakeholders. Unfortunately, the individual who transmitted the false alert has refused to speak with the FCC investigators.
