OKLAHOMA CITY - Authorities say a medical helicopter crashed early Friday morning in in northwest Oklahoma City, killing two people and injuring a third.
It happened shortly before 5:45 a.m. Friday in the parking lot of a nursing home near Wylie Post Airport.
Neighbors reported hearing a loud explosion when the EagleMed helicopter crashed.
The Oklahoma City Fire Department confirmed two people on board were killed in the crash. A third person was critically injured.
EMSA transported two people from the scene. The second patient was a bystander who rushed over to help and sustained a minor injury.
None of those onboard the helicopter were patients.
The helicopter reportedly had just taken off from a nearby hospital when it crashed.
Oklahoma City Fire Department Battalion Chief Marc Woodard said the chopper was en route from an Oklahoma City hospital to pick up a patient 70 miles away in Watonga.
Woodard says two men, including the pilot, were killed in the crash.
Witnesses say employees from the St. Ann Nursing Home pulled the survivor from the wreckage.
The Federal Aviation Administration says the cause of the crash is not known and it is under investigation.
FAA investigators are traveling to the scene Friday and the National Transportation Safety Board has been notified, said FAA spokeswoman Lynn Lunsford.
The NTSB will lead the investigation because it was a fatal accident.
Lunsford said preliminary information indicates the helicopter was not in contact with air traffic controllers at the time of the crash.
