Historical information

The PZL.37 Łoś (English: "Elk") was a Polish twin-engine medium bomber, used in the defense of Poland against the Nazi German Invasion in 1939.

The Bf-109 D was the standard version of the Bf-109 in service with the Luftwaffe during the period just before World War II. Despite this, the type saw only limited service during the war, as all of the 235 Bf-109 D still in Luftwaffe service at the beginning of the Poland Campaign were rapidly taken out of service and replaced by the Bf-109 E, except in some night fighter units where some examples were used into early 1940.

The Polikarpov I-16 was a Soviet fighter aircraft of revolutionary design; it was the world's first low-wing cantilever monoplane fighter with retractable landing gear to have attained operational status and as such "introduced a new vogue in fighter design." The I-16 was introduced in the mid-1930s and formed the backbone of the Soviet Air Force at the beginning of World War II.
