Hawaii emergency management officials knew for years that an employee had problems performing his job. Then, he sent a false alert warning of an imminent missile attack earlier this month. The problems in the Hawaii Emergency Management Agency went beyond one troubled employee. The FCC said the state emergency agency has taken steps to try to avoid a repeat of the false alert, requiring more supervision of drills and alert and test-alert transmissions. Once the employee sent the false alert, he was directed to send a cancel message but instead "just sat there and didn't respond," the state report said.
