Sadly Gp Capt Pickard DSO** DFC MiD never got a chance to try the effectiveness of his smock.
What a guy! Target for Tonight, Op Biting (Bruneval), Amiens prison, etc., etc.. Years ago I visited his grave in Amiens - he's buried alongside his Nav, Flt Lt Broadley DSO, DFC, DFM, and the French people make sure they're looked after properly.
