The War File: The Stuka Junkers JU87 Divebomber (2006) DVD
 
After the German Luftwaffe was reformed in February 1935 the four-and-a-half years that followed saw it transform almost beyond recognition. By the time the Second World War broke out in September 1939 the Luftwaffe had become one of the strongest and most battle-experienced air forces in the world.

The Germans quickly realized the tactical importance of dive-bombing and, under guidance from Colonel General Ernst Udet, the Luftwaffe began to develop a host of highly-advanced dive bomber aircraft.
