Sioux Falls emergency responders are brushing up on their skills in case a plane crash were to happen in the city.
Dozens of people are involved in Thursday's disaster drill which is being held at Joe Foss Field in Sioux Falls.
The fake plane crash is a way for departments to test the emergency plan and to make sure victims get to a hospital quickly.
Local agencies do these drills once a year.
"For all of us who on a daily basis don't work together, it's a good opportunity to get together and make sure we're all working to accomplish the same goal, it's extremely important," Tim Rave with Rural Metro Ambulance said.
Agencies from all over the city including the Sioux Falls police and fire departments, Rural Metro Ambulance, the Air National Guard and the airport authority are taking part in Thursday's drills.
