Authorities say a retired Air Force pilot from Arizona was the person killed when a small plane crashed in a Union County farm field on Sunday.
The Union County Sheriff's Office said Monday that 44-year-old Matthew Hayden, of Phoenix, died Sunday night when the Cessna 421B multi-engine plane crashed off U.S. Route 42 near the border of Union and Delaware counties.
Union County Sheriff Jamie Patton says the former Air Force pilot took off from Dayton International Airport on Sunday evening and was headed to Delaware Municipal Airport when the plane crashed shortly before 6 p.m.
Patton says the plane was owned by Classic Solutions Company Inc., out of Bakersfield, California.
An investigator with the National Transportation Safety Board says it's too early to determine what caused the crash.
