The
Savoia-Marchetti SM.79 Sparviero (Italian for
sparrowhawk) was a
three-engined Italian
medium bomber developed and manufactured by aviation company
Savoia-Marchetti. It may be the best-known Italian aeroplane of the
Second World War. The SM.79 was easily recognizable due to its
fuselage's distinctive dorsal "hump", and was reportedly well liked by its crews, who nicknamed it
il gobbo maledetto ("damned hunchback").
