The Ju 52's were used in large numbers in the occupation of Austria and Czechoslovakia and in the forefront of the invasions of Norway and Denmark, and when Holland was invaded, although this time many were destroyed.
The final German airborne invasion, that of Crete, was the most costly of any undertaken by the Luftwaffe and a third of the 500 Ju 52's operating from Greece were destroyed or badly damaged. In the Russian campaign the Ju 52 transports played an important role. This aircraft although based at the Luftwaffe multi-engine flying school in Norway was pressed into emergency action on the Eastern Front in December 1941.
