Żwirko and Wigura – these two names usually appear in tandem. Most Poles probably know them, as they are both symbols of success and tragedy. Franciszek Żwirko, a pilot in the Polish Army, and Stanisław Wigura, an engineer from the Warsaw University of Technology, formed an aviation duo that filled the people of the Second Republic with pride. On the RWD aircraft constructed in Poland, they achieved numerous victories in sky sports competitions. The pinnacle of their achievements was victory in the Challenge competition in 1932, whose route, crossing almost the whole of Europe, began and ended in Berlin. Żwirko and Wigura's string of successes was soon interrupted by an accident that sank into the collective memory of Poles. On the 90th anniversary of the legendary duo's first place in the Challenge, we present materials dedicated to this feat. To download them, click on the PDF symbol.
