At about 10:20 MST, a Cessna 172RG crashed near Prescott, killing the flight instructor and commercial student pilot. The flight originated from Prescott about 09:15 and was scheduled to return by 12:00. When the airplane failed to return, a search of the practice area revealed the crash site. During examination of the wreckage site, the left wing tip navigational light was found in a ground scar about 45 feet west of the main wreckage. The underside of the fuselage was crushed upward uniformly from the engine cowling aft to the tail cone, and the wing carry-through structure had collapsed into the cabin.
