In 1918 SIA was renamed Fiat Aviazione, which was commented in the 1919 issue of Jane's All the World's Aircraft as follows:
The initials F.I.A.T. stand for Fabbrica Italiana Automobili Torino, and
the word 'Fiat' in pure Latin, means 'Let it Be' or 'So Be it', which,
freely translated, indicates that the F.I.A.T. is undoubtedly 'It'.
The word 'Sia' in modern Italian also means 'Let it be so', with a
precisely similar connotation to the word 'Fiat'.
The play on the initials is ingenious.
The pictured aircraft was designated SIA 1200, but also referred to as the SIA 14 B."
