Analysis

The pilot attempted to pull back on the stick during the takeoff run, but was unable to move the control. He stated that he used both hands, but was still unable to move the control stick. The airplane traveled off the end of the runway where it became airborne after contacting a ditch. The airplane then settled into a corn field and a fire ensued. The reason for the control stick binding could not be determined due to the extensive fire damage to the airplane.
