In 1908 Enrico Pini (born in Milan in January 1889), was in Paris during time when Wilbur Wright presented their airplanes. He became excited and remained influenced by aviation. He abandoned his normal activities and followed the American aviator, with such interest as to attract attention and sympathy of Wilbur Wright, who wanted to reward him by taking him as a passenger in a short flight. Then Pini decided to build himself an airplane, he designed one, a monoplane-biplane that best met his needs for aesthetics rather than technical ones.

In Milan, Enrico Pini had a brother, engineer Adolfo Pini, who was five years elder, he was an electrical engineer and occupied a responsible position at the Edison Electric Company. Bothe brothers started to build a full size machine according to Enricos drawing and with help of Adolfos fundings (this sum was to be used for the expenses of his marriage, which was therefore postponed), Adolfo even resigned from Edison`s company to dedicate himself fully to the project.

The brothers built the machine at the Bezzi`s factory, he was an industrialist, who owned an electric motor factory. Designed Enrico Pini, its planes were so arranged as to widely separate a large rectangular monoplane wing, then to add a small horizontal plane above the gap. All year 1909 was dedicated to the creation of the airplane, the assembly of which took place in the hangar of Societa Restelli, which built the Rebus engines, located in Piazza d’Armi nuova. In turn, the uncle and godfather of the two brothers Adollo, wanted to help them by providing them with the engine unit, a three-cylinder fan-type Anzani fan of about 25 HP, the kind used by Bleriot in his famous crossing of the Channel.

At the end of 1909, on 15th November, it was inaugurated in Milan the first exhibition of Italian Air Force “1a Esposizione Italiana d’Aviazione” organized by the Gazzetta dello Sport, at the vast halls of the Splendido Corso Hotel. The Pini brothers exhibited the model of their aircraft that was awarded by the jury with a bachelor’s bronze medal. In the spring of 1910 finally they began testing, pilot was Enrico, but at first the machine rarely reached the desired speed, it was only taxiing, the engine was underpowered. They made some improvement of undercarriage. With the daily trials and modifications aimed at improving the performance of complex propulsion and weight reduction, the device gradually lengthened its hops up to make small flight in height ranging between 50 and 80 cm from grass surface and a length variation from 200 to 500 meters.

Unfortunately the financial means of the two brothers were soon at the end, in view of their uncle would not hear of poor results to come to the aid; they tried to borrow, but even this was limited by the lack of trust that was fed to the success of the company (Bezzi was the same creditor to over six thousand liras) and therefore the tests had to be suspended and the two unfortunate inventors, despite all the sacrifices and renunciations that were subjected to succeed in their intent, reluctantly abandoned their aviation activities. The autumn saw the device removed and deposited in a cellar and was eventually sold as scrap.

A manufacturer from Milan, Ercole Marelli, which had seen the equipment of the Pini brothers had been appreciated, rather than the qualities of the aircraft itself, the brilliant and original construction, the engineer then offered a job in his company. Enrico Pini, after the bitter disappointment, continued in his business with bold new initiatives, and finally, helped by luck managed to form a solid financial position.
