One of the victims of the tragic helicopter crash that killed billionaire Chris Cline insisted on being aboard the doomed flight to help her friend, Cline’s daughter, Kameron, who’d fallen ill, the young woman’s mother said.

Delaney Wykle, 22, who’d recently passed her nursing board exam, had traveled to the coal tycoon’s private island in the Bahamas to hang out with her childhood best friend, Kameron, said mom Paula Wykle.

Florida’s WPBF-TV reported that it was 22-year-old Kameron who had a medical emergency, prompting her dad to try to rush her to a Florida hospital in his chopper.

The heiress’ best friend insisted on coming along in case she could lend a hand, Wykle’s mother said.

“She got to practice nursing for one day,” Paula Wykle said sadly, calling her daughter “smart, loving and one of the best friends anyone could ever ask for.”

In addition to Cline, his daughter and Wykle, two other college friends of Kameron’s, pilot Geoffrey Lee Painter, 52, and another man, David Jude, 52, of Kentucky were killed when the helicopter plunged into the ocean July 4.

Accident investigators in the Bahamas announced that they had pulled the Agusta AW139 helicopter from the ocean late Saturday.

The aircraft is expected to be taken to Fort Lauderdale and then to an accident investigation facility in Fort Pierce, Fla.

Authorities have said it’s too early to draw conclusions about the cause of the crash. They don’t believe a distress signal was made and only began searching for the helicopter after it was reported missing.
