MIDDLETOWN, Ohio >> A woman has died from injuries she suffered when she walked into a spinning airplane propeller at a southwest Ohio skydiving business.

Twenty-four-year-old Sarah Rhoads died Tuesday at a Dayton hospital, where she had been flown after Sunday’s accident in Middletown. Authorities said she suffered severe head injuries.

She had been office manager for three years at Start Skydiving. It operates near Middletown Regional Airport.

Owner John Hart says it’s the first time the business has had such an accident. He says it can be difficult to see fast-spinning propeller blades.

The Federal Aviation Administration says it will investigate the accident.
