CHARLOTTE -- First responders in Charlotte trained for what could happen if one plane crashed into another on the taxiway.

On Sunday at Charlotte Douglas International Airport, multiple area agencies responded to a fire and spent time triaging about 100 faux passengers, who had injuries ranging from minor to severe.

The disaster drill is a Federal Aviation Administration requirement and must be performed every three years.

The airport fills out an FAA-specific checklist, which is provided to them and kept on file to prove their readiness in these types of situations.
