This biography, written by his son, is of the first ever Italian pilot who was also a pupil of Wilbur Wright. It has been translated into a sort of Italian-English which is very agreeable. Calderara was a professional sailor and pioneered the concept of towing gliders behind warships for observation purposes, in spite of much opposition from the higher ranks. He did it because he saw this as a preliminary step towards powered flight. The Germans did it successfully with submarines in World War II. It is a good story with much interesting background about living in Italy during two wars. There are a good number of unusual family photographs as well.
