accidentally pressed the wrong button during a shift change. they were testing the system and they have been testing the system here in hawaii, but never anything like this. the test is an actual emergency siren, an attack siren that goes off and they have told the population here what it's all about, but, indeed, in this time, it wasn't the attack system that went off. it was a message to television viewers. it was a message through the radio, and a text message on the cell phone. as emergency managers try and figure out how to make sure this never happens again, they are apologizing, saying this is human error, but it did create quite a bit of emotion here in hawaii. victor, christi? >> sara, thank you so much. cnn producer amanda golden is with us now. she was in hawaii yesterday when this happened. amanda, i'm glad you're okay. but help us understand what it was like there when this alert first went out. >> yeah.
