The RWD-14 Czapla was a Polish accompanying aircraft (in cooperation with the army) of a mixed structure, in the high wing configuration, with a fixed undercarriage. The drive was provided by a single engine PZL G-1620B Mors II with 470 hp. The flight of the prototype took place in 1936, and in the years 1938-1939 serial production continued, ending with the production of about 65 aircraft of this type. The armament was 2 machine guns: 7.7 mm Vickers and 7.92 mm wz. 33.
The RWD-14 Czapla aircraft was created in response to the demand announced in 1933 by the Polish military aviation for a new accompanying aircraft, which was to replace the Lublin R.XIII machines in the line. At the same time, the command of the Air Force treated the RWD-14 as a transition plane, waiting for the LWS-3 Mewa to be put into production. The Heron had better performance than its predecessor, but at the same time it differed significantly from the needs of the battlefield at that time, which makes it even more reasonable to build only about 65 aircraft of this type. It should be added, however, that the RWD-14 Czapla was an airplane with short take-off and landing features, and also had folding wings, which facilitated hangar. Aircraft of this type took part in the September campaign in 1939. 49-51 machines entered the fight, of which approx. 35 were lost in battle, and approx. 11-14 pieces went to Romania. Single copies were seized by the Soviet and German troops.
The PZL TS-11 Iskra is a modern Polish training and combat aircraft. The prototype flight took place in 1960. Serial production continued in the years 1963-1987, ending with the production of 424 copies of this aircraft. The drive (since 1969) is provided by a single engine jet WSK SO-3 . The plane's top speed is 720 km / h, and the maximum range is 1,250 kilometers. The deck armament is a single 23mm NS-23 or NR-23 cannon.
Along with the wide introduction of jet aircraft to Polish aviation, it became necessary to construct an adequate training aircraft. The plants were responsible for its development and production WSK "PZL Mielec", and its main designer was Tadeusz Sołtyk. The new aircraft turned out to be a successful design with good performance, relatively low reliability and low operating costs. Many variants of this aircraft were created in the course of serial production. The first mass-produced version was the Iskra bis-A, still powered by the SO-1 engine. Shortly after, the Iskra bis-B version appeared, which was already a training and combat model with the possibility of taking overhead weapons. The Iskra R version, i.e. the naval reconnaissance version, or the Iskra bis D - training and combat version, also entered service. A civilian version without weapons called the Iskra Jet was also created. The military users of the TS-11 Iskra aircraft were Poland and India. In the civil version, the planes went to, among others, the USA or Great Britain.
