Officials Hold Emergency Preparedness Drill At Universal Studios

LOS ANGELES, CA - APRIL 19: A member of the US Army 9th Civil Support Team prepares to enter a hazardous crash zone during an exercise simulating mass casualties from the collision between a single-engine Cessna and a commercial airliner with levels of radioactivity present at the set built for the filming of ?War of the Worlds? at Universal Studios theme park on April 19, 2007 in Los Angeles, California. The exercise is taking place at the conclusion of three days of large-scale disaster preparedness exercises, based on the scenario of a terrorist attack in the wake of an earthquake. The exercise, called Operation Vector, was hosted by the California National Guard and is designed to promote interagency cooperation during a disaster or attack and evaluate the performance of responding agencies. It is expected to be the first in a series of similar events at landmark sights. (Photo by David McNew/Getty Images)
