I needed a laugh, thanks for posting. I could question his logic line by line, but I think it sufficient merely to note that the RAF's contribution is numerically small but still greater than the Navy's.
One question did spring to mind reading his article though. He labels himself, or is labelled in the article an 'air ace'. I always thought the criteria for 'Ace' status was 5 kills and yet his own Wiki entry with his citation only notes 3; has the criteria been watered down or is he just a playing Walt?
