Honolulu CNN  — 

It was a beautiful morning, like most, on the island of Oahu: 79 degrees with a big, bright sun. I was at a marina with my family on Kaneohe Bay, blowing the last bits of air into an orange inflatable raft, when the alert came. All caps: “BALLISTIC MISSILE THREAT INBOUND … NOT A DRILL.”

I could feel the blood stand still in my body, the breath leaving my chest, a numbness coming over me. Is this really happening? I asked a man next to me, “You also get this?” He had. Others nearby started running. I did, too.

Find your family, I thought. My older brother, my mom and a cousin were at the car. Another cousin was missing. He’s loading the boat, his wife said. I’ve been calling his name but I can’t find him, she said. I ran for the dock. “Neal!” I shouted.

There he was. With no cell phone on him, he still had blue ocean on his mind, not impending death. I hustled him back to the car and read him the message. His jaw dropped.

Visitors to this marina in Kaneohe Bay, Hawaii, left the water and ran for cover after receiving the missile alert Saturday morning.

There was quiet and confusion. No alarms sounded or blared directions. Where do we go now? How long do we have? How long would it take for a missile to arrive from North Korea? The US would surely shoot it down, right?

It wasn’t hysteria – there were no shrieks or sobs – but people were scared. A child sat on the concrete floor, his head in his knees, rocking back and forth. A young man appeared to have a mild panic attack, his father trying to calm him. My brother called his wife, at home with their newborn baby in Honolulu.

My breathing was ragged. My voice shook as I told a group of strangers that I worked in news. I haven’t heard anything, I told them. My assignment desk is checking with the Pentagon, I said. I imagined a fiery missile hurtling through space above us. Minutes had gone by. Someone had to tell us what was happening soon. We waited in shock. I checked my work email incessantly, hoping for an update.

Visitors took cover in this hangar after the missile alert was issued.

“We’re going to war,” a man next to me said. That consumed my thoughts for the next few minutes.

Then, 15 minutes after the alert arrived, the tweets came in. One from US Rep. Tulsi Gabbard of Hawaii; a second, a minute later, from the state’s emergency management agency. False alarm. I announced the news to the hangar. The air in the room changed. Color entered back into people’s faces.

As more tweets rolled in from local officials and politicians, the reality set in. We lifted the doors back open and the sun shown in. It was still bright ou
