A small plane’s propeller severed a woman’s arm in front of her horrified husband — the craft’s pilot — on a runway in the Florida Keys, according to officials and reports.

The gruesome scene played out around 8:45 p.m. Saturday when the pilot tried to taxi the rented single-propeller Cessna 172S along Key West International Airport only to find it wouldn’t budge, the Miami Herald reported.

Leaving the plane running, the pilot, identified by the paper as Walter Gray, got out to look for the issue, according to the Monroe County Sheriff’s Office.

Though Gray told her to stay in the plane, Rebecca Lynn Gray, 45, also got out and moved to help free one of the plane’s wheels from a chock, a block used to keep wheeled craft steady, the report said.

As she was doing so, she was sliced by the single-engine plane’s propeller.

The Monroe County Sheriff’s Office said that Gray lost both an arm and a foot, but Florida Highway Patrol, which is leading the investigation, told the Herald that she only lost an arm.

Gray, of Naples, Fla., was airlifted to a hospital in Miami, where she’s reportedly listed in stable condition.
