Question for you WW II Air Force gurus...

[82Trooper]

Hello:
I am looking for some assistance on a new research quest I have undertaken. I recently discovered my long time army airborne friend's grandfather wrote a book about his time as a turret gunner in WW II. His name is Bill Williams and the book was called "Five Miles High and forty Below". (Awaiting my hard to find copy from a seller on Amazon.)

I want to do some more research on his life and experiences. I located his obituary, which included rather dashing photograph of Mr. Williams. Specifically, can anyone help me identify the patches on his flight jacket...the left shoulder and the left front above the pocket?





Any assistance or references would be appreciated. Thanks.
Mike
