At one point, crew members were “pinned to the ceiling” of a medical helicopter en route to Children’s Hospital of Philadelphia that made an emergency landing Jan. 11 on the grounds of a Drexel Hill church, reports Deanna Durante and Brian X. McCrone for NBC10 Philadelphia.

A preliminary NTSB report indicated the helicopter flipped in flight as it was traveling from Chambersburg, Pa. to CHOP, transporting a two-month-old girl for medical treatment.

The onboard medic and a nurse caring for the infant said there was a “loud bang” about 10 minutes before the aircraft was supposed to land at CHOP, according to the National Transportation Safety Board report.

The noise was followed by the jarring movements of the helicopter.

“The medic said that the helicopter rolled inverted, perhaps multiple times and that he and the nurse were ‘pinned to the ceiling’ and internal communication was lost,” the report said. “The helicopter was leveled, the patient was secured, the crewmembers secured themselves in their seats, and they braced for landing.”

The helicopter struck Burmont Road at Bloomfield Ave. and slid onto the front grounds of Drexel Hill United Methodist Church.

None of the four people aboard suffered serious injuries and the pilot, identified as Daniel Moore, was able to land the craft without striking houses, wires, trees, cars, pedestrians, or the church.

The infant was transported to CHOP by ambulance. Others on board were treated at area hospitals and released.

The pilot was taken to Presbyterian Hospital in Philadelphia for treatment of more significant injuries, including broken ribs, vertebrae, and cracked sternum, according to an interview with his father at Fox 29 News.

Moore has 27 years of experience flying helicopters and is a commercial pilot.

He was released five days after the crash to the applause of police and fire personnel and the hospital’s medical team.

He told the news media that he had “God as my co-pilot that day, and we took care of the crew and we landed in His front yard, so that was kind of nice.”

Several people, including Upper Darby Police Superintendent Timothy Bernhardt and Drexel Hill Methodist Pastor Russell Atkinson, have referred to the landing as a miraculous occurrence.

A full investigative review will be released in several months. A typical NTSB investigation takes 12 months or more to complete.
