The warning
For 38 minutes, everyone in Hawaii believed a nuclear missile was incoming.
This is The Point of Failure, episode nine.
January 13, 2018, 8:07 in the morning. Every phone in Hawaii screamed at once. Ballistic missile threat inbound. Seek immediate shelter. This is not a drill.
The drill
It was a drill. During a shift change, an employee at the emergency agency was meant to run a routine test. On the screen, the test alert and the real alert sat in the same menu. Two options, side by side, one click apart.
The missing retraction
The wrong one was selected. And investigators later found the drill itself was confusingly scripted. The employee reportedly believed it was real.
Point of failure
But here is the failure that turned a mistake into 38 minutes of terror. There was no prepared way to say false alarm. No cancel template existed. They had built the alarm and never built the retraction.
So while officials scrambled, parents lowered children into storm drains. People made goodbye calls. For 38 minutes.
The safeguards
The fix afterwards took days, not years. Separate the drill from the live system. Require a second confirmation. Prepare a false alarm message in advance. Every one of those could have existed on January 12.
Every failure has a story. Every story was preventable. I'm Kevin. See you on the next one.
