Air ambulance helicopter crash kills all on board

An air ambulance helicopter crashed in Ohio Tuesday, killing all three crew members on board, according to a company official.

The Survival Flight Inc. helicopter was headed to pick up a patient from a hospital in Pomeroy, Ohio, at the time of the crash, according to the Federal Aviation Administration (FAA).

The crew members have been identified as pilot Jennifer Topper, 34; nurse Bradley Haynes, 48; and nurse Rachel Cunningham, 33, according to the Ohio State Highway Patrol.

"We are obviously devastated," said Andy Arthurs, vice president of EMS services for Survival Flight Inc. "Our first concern is for the crew members and their families."

The crash happened at 6:50 a.m. in a heavily wooded area of Zaleski, Ohio, which is located about 70 miles southeast of Columbus, according to National Transportation Safety Board (NTSB) spokesman Peter Knudson.

The wreckage of the helicopter -- which had taken off from a hospital in Grove City, Ohio -- was found at about 10:15 a.m., according to the highway patrol.

No one on the ground was injured, highway patrol officials said.

The cause of the crash was not immediately clear.

An investigator from the NTSB will arrive in Ohio on Wednesday, Knudson said.

From 2009 through November 2018, there were 75 medevac helicopter accidents, 27 of which were fatal, according to the NTSB.
