He is Pietro Bonannini. My italian is terrible, but if I got it right he was an ace who was not a pilot, but a machine gunner.
Correct on both accounts!
He served as a gunner on recce seaplanes Fiat RC14 and Cant Z506, which usually flew alone and unescorted. He has 8 confirmed kills of RAF fighters (Spits, Hurris, Beaus) and is the only Italian non-pilot ace of WW2. On one instance when his dorsal 12,7 Safat jammed, he dismonted the ventral 7,7 Scotti and fought on. Ironically he survived the war only to die postwar in civilian air crash.
Floor is yours, Shakaali!
