An attempt to outline the history of the origin and use of the first common motor aircraft of the design pair Ing. Pavel Beneš and Ing. Miroslav Hajn.
History of aircraft production in Avia from 1918 to 1939. Combined with an overview of all manufactured and designed aircraft along with TTD.
The first aircraft of Czechoslovak construction, which appeared in the sky of civil war-torn Spain, became the fighter Avia BH-33E. The only specimen arrived on the Iberian Peninsula at the end of August 1936. It can serve as a textbook example of how the Republican Air Force gained combat aircraft after the outbreak of hostilities. In addition, it can also be used as an example of the sad fact that the effort made did not match the final effect. The famous saying " For a lot of money, little music " is suitable for the Avia BH-33E.
