(CNN) -- Four people died Friday in a medical helicopter crash near Clay County Regional Airport in Mosby, Missouri, the Federal Aviation Administration said.
The aircraft was carrying three crew members and one patient, Lynn Lunsford of the FAA told CNN.
Video from the crash scene showed the chopper's shattered wreckage lying in a grassy area, emergency vehicles surrounding it.
The helicopter had refueled at the airport and was en route to Liberty, Missouri, about 10 miles away, Lunsford said.
