My first jet instructor, at Leeming 1961-62, was Flt Lt Pete (Piotr?) Bobrowski. We never found out his detailed story, but were led to understand that he had been in the Polish Air Force pre-1939. He had a chestful of RAF WW2 ribbons. After Leeming I never saw him again, but I believe he ended up as an Ops Officer at Brize in the late 70s and died while serving there. I have checked the list of BoB pilots, and he is not shown there. I have fond memories of "Bobs".
