A Shattuck man died when his ultralight aircraft crashed east of Shattuck on Monday night, said the Oklahoma Highway Patrol.
David W. Kelln, 37, was pronounced dead at the scene of the crash from head and internal trunk injuries, the OHP said.
Kelln was flying a Rans S-18 Stinger ultralight single engine aircraft going southwest when, for an unknown reason, the aircraft "descended into the ground," the OHP said. The crash happened around 7:30 p.m. on a county road two miles east of Shattuck.
The OHP said the Federal Aviation Administration would continue an investigation into the accident.
The crash was initially investigated by OHP troper Cody Rehder, assisted at the scene by the Ellis County Sheriff's Office, Shattuck Police Department, Fire and Rescue and EMS.
