At 4:21: “Many believe that brain damage from the head wound he received in July 1917, along with cumulative combat stress, caused him to disregard some of the precautions that made him invincible in the sky, resulting in poor judgment during his final combat."

At 7:51 he kinda looks like KK Downing.
