WITNESSES HEARD THE VINTAGE WWII TRAINER TAKING OFF AT NIGHT. THEY REPORTED THAT DURING THE INITIAL CLIMB, THE ENGINE SOUND VARIED FROM HIGH TO LOW RPM 4 TIMES, THEN THEY HEARD THE AIRPLANE COLLIDE WITH THE TWO-STORY APARTMENT BUILDING. A PILOT APPROACHING TO LAND AT THE DEPARTURE AIRPORT REPORTED SEEING THE ACCIDENT AIRPLANE AT LOW ALTITUDE AND '...NOT CLIMBING OR CLIMBING AT A VERY SHALLOW ANGLE.'

METALLURGICAL EXAMINATION OF THE FRACTURES BY THE SAFETY BOARD REVEALED FEATURES CONSISTENT WITH OVERSTRESS SEPARATION.
