The Dornier Do 17 is a German twin-engine bomber aircraft that was first introduced in the late 1930s. Known for its distinctive "flying pencil" shape, it was designed for high-speed bombing missions during World War II. The aircraft was primarily used by the Luftwaffe and played a significant role in early air operations. With a wingspan of about 15 meters, the Do 17 could carry a payload of up to 1,000 kg. It was equipped with various armaments, including machine guns for defense. Despite its initial success, the aircraft became increasingly vulnerable as the war progressed, leading to its eventual retirement.
