The Kent County sheriff's office says a full-scale plane crash simulation will take place in Caledonia Township.
The exercise is set for Saturday at the Davenport University and Farmers Insurance Group campuses.
The purpose is to prepare Kent County emergency responders and trained volunteers for a large-scale emergency.
The simulation involves a 90-passenger commercial airplane crash with an imitation airplane, debris and 90 volunteers role-playing wounded or deceased victims from the mock crash.
Local emergency responder teams are to be on site and fully deploy their equipment and personnel to practice their response.
Funding is being provided by the Department of Homeland Security via the Grand Rapids Metropolitan Medical Response System.
