The Unfortunate Tale of the Underwhelming S.I.A. 7B
Aircraft design was more of an art than a science during the First World War. In many posts I have written about the problems experienced by Austrian designers while laboring down dead ends. The one saving grace for Austria was the inability of Italy to develop winning fighter and reconnaissance aircraft designs. Both Italy and Austria relied on designs created by their allies. For the most part Italy built planes from French designs. These include Macchi built versions of the Hanriot H.D.1, Nieuport 11-17, and the S.P.A.D. S.VII.
As with most examples the forward fuselage is bare metal. The height of the engine cover was very problematic for pilots since it blocked his forward field of vision.The roundels have a thin white border.
A Short History of the S.I.A. 7B
The Società Italiana Aviazione 7B was designed to replace the earlier pusher planes in service with the Italian air force. The SIA 7b was tested and approved for production in early 1917. The initial production aircraft were delivered to the reconnaissance squadrons in the summer of 1917. A later version had a different fairing of the fuselage decking. the SIA 7B proved extremely disappointing. Its workmanship was bad, and it suffered from wing failure, losing its wings in flight. Another fatal problem involved the Fiat engine mounted on this model which was notoriously troublesome. It was known to suffer from backfire at the carburetor and catching fire, much to the discomfort of the air crew. After a string of many fatal accidents this design was permanently withdrawn from service in June of 1918.
