Hajn was first a founder and chief designer at Avia, along with Pavel Beneš, in 1919. The two began repairing planes in a workshop within the complex of an old sugar factory in Prague.[2] One year later, they designed their first two-seater plane, the Avia BH-1. From 1923 to 1925, the two developed the Avia BH-7, BH-9, and BH-11 monoplanes, launching the era of biplane fighters. The BH-11 won the Coppa d' Italia prize. Three years later, their Avia BH-21 fighter was considered one of the world's best planes.[3] In 1930, Hajn and Beneš came to ČKD-Praga. The first aircraft they designed was the Praga E-39 in 1931.[1] References1. ^1 {{cite web|url=http://www.rsmodels.cz/?link=view&id=92002&PHPSESSID=d054c4d1863125b0d1f32f513c4f1c79|title=Praga E-39 Czechoslovakia - Luftwaffe|publisher=fosvion.com |language=German|accessdate=31 January 2009}} {{authority control}}{{DEFAULTSORT:Hajn, Miroslav}}2. ^{{cite web|url=http://www.avia-as.com/index.php?m=17|title=AVIA: History|publisher=AVIA|accessdate=31 January 2009}} 3. ^{{cite web|url=http://www.czechinvest.org/data/files/aerospace-2008-99-en.pdf|title=Aerospace Industry in the Czech Republic|publisher=CzechInvest|accessdate=31 January 2009|archiveurl=https://web.archive.org/web/20081203120101/http://www.czechinvest.org/data/files/aerospace-2008-99-en.pdf|archivedate=3 December 2008}} 6 : 1894 births|1963 deaths|Czech aerospace engineers|Aviation inventors|Aerodynamicists|Inventors |
