CASA GRANDE, Ariz. (AP) - Authorities have released the names of two men killed in the crash of a private plane at Casa Grande Municipal Airport in southern Arizona.
The twin-engine Beechcraft Air King went down Wednesday morning as it was landing and burst into flames north of a runway.
The Pinal County Medical Examiner's Office officially identified the victims Friday as 51-year-old Stephen J. Stafford of Green Valley and 65-year-old Del V. Steinbronn of Tucson.
Authorities say Stafford was a certified flight instructor while Steinbronn was a retired private practice urologist. They say both men had many years of flight experience and died from injuries sustained from the crash's impact.
The small plane was registered to a Tucson company.
The crash is being investigated by the Federal Aviation Administration and National Transportation Safety Board.
