Human Factors
Aircraft of unknown type overtook me. In cruise; I looked out my right window and saw the aircraft approaching from my 4 o'clock at a range of 200 feet; approximately 100 feet below me. Before I ever had the chance to take evasive action; the aircraft had already passed behind me; nearly striking my empennage with approximately 50 feet between the two aircraft.
