Our dependence on air travel was sharply put into focus on 9/11. But did you know Hawaii was one of two dozen U.S. cities that had an emergency management system in place that went from training drills to a real-world terrorist event? Salvatore Lanzilotti was head of Honolulu Emergency Medical Services under then-mayor Jeremy Harris. This weekend's 9/11 anniversary stirred his memory of Hawaii's state of readiness to deal with a terrorist attack back then. But it also set the framework to prepare for other potential disasters and biological attacks, and high-security events like the Asia-Pacific Economic Cooperation meeting of world leaders that was held in the islands. The threats are still out there and it stands to reason we keep our resiliency in check.
