The second recent blunder in Hawaii's planning for a possible North Korean nuclear or otherwıse attack left islanders shaken after an emergency alert warning of an imminent strike sounded on hundreds of thousands of cellphones.
People waited for nearly 40 minutes to get an update, and then came the second mobile alert: someone hit the wrong button, there was no missile.
Some people abandoned cars on the highway and others gathered in the interiors of their homes to wait for what seemed like the inevitable, a blast that would cause widespread death and destruction.
The message sent statewide just after 8 a.m. Saturday read: "BALLISTIC MISSILE THREAT INBOUND TO HAWAII. SEEK IMMEDIATE SHELTER. THIS IS NOT A DRILL."
The Hawaii Emergency Management Agency's administrator, Vern Miyagi, said he took responsibility for the mistake. He said officials would study the error to make sure it doesn't happen again.
The state adjutant general, Major General Joe Logan, said a written report would be prepared. State lawmakers announced they would hold a hearing next Friday, and Federal Communications Commission Chairman Ajit Pai said on social media the panel would launch an investigation.
The backlash from lawmakers was swift.
Hawaii House Speaker Scott Saiki said the system Hawaii residents have been told to rely on failed miserably.
"Clearly, government agencies are not prepared and lack the capacity to deal with emergency situations," he said in a statement.
Hawaii Senator Brian Schatz tweeted the false alarm was "totally inexcusable."
"There needs to be tough and quick accountability and a fixed process," he wrote.
"This false alert is detrimental to the integrity and trust of the emergency management system," said state Senator Donna Mercado Kim.
The Hawaii Emergency Management Agency tweeted there was no threat about 10 minutes after the initial alert, but that didn't reach people who aren't on the social media platform. A mobile alert informing of the false alarm didn't reach cellphones until about 40 minutes later.
Many people said they are resigned to the fact that there is little they can actually do if a missile was to be launched toward the remote island chain, especially with only about 15 minutes of warning time for a strike from North Korea.
With the threat of missiles from North Korea on people's minds, the state reintroduced the Cold War-era warning siren tests last month that drew international attention, but there were problems there, too.
Even though the state says nearly 93 percent of the islands' 386 sirens worked properly during the December test, 12 mistakenly played an ambulance siren. In the tourist hub of Waikiki, the sirens were barely audible, prompting officials to add more sirens there and reposition ones already in place.
Hawaii officials apologized repeatedly and said the alert was sent when someone hit the live alert button instead of an internal test button during a shift change.
"Today is a day that most of us will never forget," said Hawaii Governor David Ige. "A day when many in our community thought that our worst nightmare might actually be happening. A day when many frantically tried to think about the things that they would do if a ballistic missile launch would happen."
The agency did not have a plan for a false alarm in place, officials said.
Ige called the mistake unacceptable
"I am sorry for the pain and confusion it caused," he said. "I, too, am extremely upset about this."
