Dear Brian,
Are you interested only in friendly fire incidents in the Allied air forces, or also in Soviet VVS? It seems to me that any book aiming to cover all period of WWII in terms of friend or foe misidentification will be incomplete without records from Eastern front. There are lots of such cases from the Soviet side. If you are interested, please contact me off-board.
Best regards,
Nikita
