National originGermany

First flight1924

The Heinkel HD 21 was a trainer built in Germany during the 1920s. It was a conventional single-bay biplane with staggered wings braced with N-type interplane struts. The main units of the fixed, tailskid undercarriage were linked by a cross-axle, and the aircraft had three open cockpits in tandem, although one of these was typically faired over. The HD 29 of 1925 was essentially similar, but was purely a two-seater.

One HD 21 (registered SE-ACY) was flown as an air ambulance by Carl Gustaf von Rosen for the Red Cross during the Italian invasion of Abyssinia in 1935. Others were flown by the Reichswehr at the clandestine aviation training facility in Lipetsk.

Airbus A321 Airliner, stretched model of the A320 family

The Airbus A321 is a member of the Airbus A320 family of short to medium range, narrow-body, commercial passenger twin engine jet airliners; it carries 185 to 236 passengers. It has a stretched fuselage which was the first derivative of the baseline A320 and entered service in 1994 about six years after the original A320. The aircraft shares a common type rating with all other Airbus A320-family variants, allowing previous A320-family pilots to fly the aircraft without the need for further training.
