An Aircraft Mishap Preparedness and Contingency Plan is underway at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida. The center's Flight Operations rehearsed a helicopter crash-landing to test new and updated emergency procedures. The operation was designed to validate several updated techniques the center's first responders would follow, should they ever need to rescue a crew in case of a real accident.
