Local and federal emergency responders launched a disaster drill today to test their ability to work collectively in a major emergency.

The test simulated a plane crash into the Fore River. The event included numerous pieces of emergency apparatus on the Veterans Memorial Briidge and closed the northbound lanes to traffic.

The drill included fire and police from Portland and South Portland, the jetport, the Coast Guard, and Continental Airlines, which agreed to participate in the drill, as well as several other federal and stgate agencies.

A full-scale jetport emergency drill is required by the Federal Aviation Administration every three years.

Following the simulation, participants met to critique the response and look for ways to improve.
