The cause of the crash is under investigation, led by Choctaw Nation Law Enforcement because the crash occurred on tribal lands. Investigators with the Federal Aviation Administration and the National Transportation Safety Board as well as EagleMed's safety team are expected to assist in determining the cause of the crash.
Hospital workers responded to the accident and provided aid and rescued the surviving victims, said Teresa Jackson, hospital CEO.
"Our staff responded extremely well to this unfortunate tragedy," she said. "We engaged our disaster plan within moments of the accident, and the response from our staff as well as the local and state emergency personnel in the area was outstanding.
A hazardous materials team was onsite late Tuesday after the crash as the helicopter's wreckage was leaking fluids. The spread of what was presumed to be fuel and hydraulic oil was contained and officials say there appears to be no immediate danger in or near the scene.
