In November 1955 the training of foreign pilots started, when specialists from East Germany arrived. But a really mass training of air crew started in 1957. Pilots, flight-engineers, flight-radio operators from GDR, Bulgaria, Romania and Hungary were trained on the Il-14. When aeroplanes with turboprop engines Il-18 and An-10 arrived, training of pilots from Guinea, Mali and Ghana started as well. From 1962 to 1972 in Ulyanovsk Higher Flight School were mastered a lot of aeroplanes such as the Tu-124, Tu-134, Tu-154 and An-24.
