SPRINGFIELD, N.J. — New Jersey State Police on Thursday identified the two men who were killed when a plane went down Wednesday on its way to Cape Cod.

The plane’s owner and pilot — Robert Winner, 69, of Marlton, New Jersey, and his co-pilot, Timothy Scannevin, 71, of Southampton, New Jersey — died in the crash Wednesday morning, according to New Jersey State Police Lt. Theodore Schafer.

The men, who were flying in a Hawker Beechcraft 58 Baron aircraft, were on their way to Barnstable Municipal Airport in Hyannis as part of an Angel Flight when the crash occurred, Schafer said.

Angel Flight is a volunteer service that provides air transportation for patients in need.

Ellen Williams, executive director of Angel Flight, told NJ.com that Winner was a volunteer with the program that provides free flights to patients needing care at distant medical facilities.

Scannevin was not affiliated with Angel Flight East, she said.

Winner and Scannevin were flying to Hyannis to pick up a patient in need of emergency cancer treatment, Schafer said, adding that he did not have any additional information about the patient.

The Federal Aviation Administration and the National Transportation Safety Board are investigating the crash. NTSB says no distress call was made before the crash.

The plane had taken off around 9 a.m. from South Jersey Regional Airport in Lumberton, about 10 miles southwest of the crash scene.
