The De Havilland DH89 Dragon Rapide was a passenger and transport aircraft built in the 1930's. The DH89 and its variants proved popular with air forces and civil air lines all over the world and over 700 were built. They continued to fly in WWII and beyond, for example with the Israeli Air Force. Some are still airworthy today.
A famous instance of its use was in 1936 when a Dragon Rapide chartered from a British airline brought General Franco from his exile in the Canary Islands to Spanish Morocco to lead the Nationalist forces in the Spanish Civil War. Several Dragon Rapides were also used by both sides' air forces in that war.
