I do not know if he suffered from THAT fire but it is likely. He suffered severe damages to the head and the upper torso hence his gratefulness that the Americans did go the extra mile and not just patched him together but flew him to a hospital in FL. (Do you have any idea why they did that?)
I remember that his left ear was halfway gone (burned) and that was the only visible evidence of his injuries. Considering the average casualties from being shot down he was lucky.
