If you happen to see what looks like a speedboat ramming a state ferry and exploding in Elliott Bay on Sunday morning, don't be alarmed — it's only a test.

More than a dozen federal, state and local agencies will simulate a terrorist attack on an out-of-service ferry heading to Coleman Dock from Bainbridge Island.

The training exercise, scheduled for between 8 and 11 a.m., is designed to test a newly formulated response plan for terrorist attacks on the water. It also will test the ability of many agencies to work together.

"For us to be able to play and drill so that we can respond, we have to make this as realistic as possible," said A.D. Vickery, assistant chief of the Seattle Fire Department.

The Seattle event will be the most visible of four exercises Sunday in the Puget Sound area. Tacoma will simulate an explosion inside a cargo container. Two other "table-top" scenarios will be simulated by officials but won't involve people in the field: terrorists taking over a cruise ship and releasing a biological toxin, and the discovery of a motorboat packed with explosives.

The goal is to see how the agencies respond to simultaneous disasters that tax the region's emergency resources. "We are planning here on a worst-case scenario," Vickery said.

Sweet, should get a good view of this from the beach near my place .... nothing says Sunday morning like low-altitude passes by attack choppers!

How do you test a "response plan" when you know in advance the attack is coming.

that would be the perfect time for real terrorists to do something across the city from where they are planning that
