The book talks about Eduardo and Giuseppe Rusjan, two brothers of the barrel maker Franc Rusjan family from Gorizia.They successfully performed first attempts of the motor flying in this part of Europe in the first years of the 20th century.

Gorizia as well as also all the the Gorisko-Gradis+AQ0-anska region together with the rest of the Slovenian regions belonged then into the frame of the Middle-European state known as multinational Austro-Hungarian Empire. Slovenian inhabitants were in majority, and in the town of Gorizia their number was approximately the same as the Italians. Fast tempo of economic and social development was enabled by tolerant international circumstances which formed also good conditions for existence of Slovenian economic and cultural organisations which were a necessary factor for ensuring material and logistic support to the developing projects of their members including Eduardo and Giuseppe Rusjan at that point of social progress.

Armed with stubbornness, professional knowledge from the domestic workshop and fast developing surroundings they started to applicative research at time relatively little known area of aircraft construction and practical motor flying hoping to grow into the Airplane factory of the Rusjan brothers. Eduardo was more capable in designing the aircraft machines, Giuseppe was handier in manufacturing them. Eduardo in contrast to his brother also tested and piloted them. Some knowledge was passed to Eduardo by scarce literature available at that time, more by his acquaintance engineer Franc Miller from Torino, and even more he learned when visiting the best world airmen meeting in Brescia in 1909.
In 1909 and 1910 the Rusjan brothers manufactured seven aircrafts which were fundamentally different in flying and constructive characteristics. The planes were called after shortened Eduardo's name EDA and followed by a consecutive number. The airplanes were tested in the meadows of Little Country west and Big Country south of the town. One can still find the airport there (Aeroporto Duca d'Aosta). They were assisted by Slovenian sport associations, craftsmen and other townspeople, most importantly also family members. Beside the mother Grazia Cabas from Medea there were five sisters and two brothers in the family.

In the second half of the year 1910 the conditions for the two brothers in Gorizia deteriorated. The surroundings did not help any more and the work conditions were no more favourable. But the ambition remained.
Circumstances connected with Eduardo's cycling activities enabled them making the acquaintance of Mihajlo Mer+AQc-ep, a wealthy photographer from Zagreb, who offered them cooperation in continuing aircraft manufacturing for sale. They moved their activities to Zagreb. First they made one airplane (the first Mer+AQc-ep-Rusjan airplane) and started with building another one (Sokol). In the first days of the year 1911 the first airplane together with Eduardo the pilot crushed during performing propaganda flying in Belgrade from the height some tens of meters. Eduardo did not survive the accident.
After the death of Eduardo, Giuseppe continued his work with Mer+AQc-ep. They manufactured some more aircrafts and trained new pilot, but there was neither commercial success nor money. That was the reason why Giuseppe emigrated with his family to Argentina, where he was successful craftsman and innovator. He is also buried there. The majority of the Franc Rusjan children also left for Argentina.
Of the entire family only Grazia Rusjan, their youngest brothers Carlo, lives in Gorizia today.
