At about 07:45 mountain time, a Cessna 172L crashed into a house and burned in Tucson, killing the pilot. The flight had taken off from La Cholla Airpark, a private residential airport, in violation of flight restrictions against VFR flight. The airplane was detected by Tucson Approach and the controller transmitted in the blind, telling the pilot to return to the point of origin. The pilot did not respond but the airplane reversed course and the transponder code changed from 1233 to 1203. About six miles south of the departure airport, the airplane crashed into the house.
