At 13:15 central time, a Beech 95-B55 crashed near Alvarado after the pilot lost control. The pilot and flight instructor were killed. The pilot was the owner of the flight school that operated the airplane, and the flight instructor was the chief pilot. The pilot, who was already multi rated, was working on proficiency. A witness reported hearing the airplanes engine sounds change, then saw the airplane in what appeared to be a flat spin at about 1,500 feet agl. The engines revved again, but the airplanes attitude did not change. The airplane landed in a flat attitude with no ground scars except those beneath it. The landing gear was extended and the flaps were in an approach position.
