saab draken
A Swedish 60s-era military jet used mainly as a fighter-interceptor. It sported a unique double delta planform, the inner delta also forming the air intake trunks for its single turbojet. Aside from its 30mm cannon, it could carry up to 4,082 kg (9,000 lb) of rockets, bombs, and air-to-air missiles. It was replaced by the Saab Gripen in the 1990s.
Due to its tailless delta configuration, the Draken was plagued by critical instability and was prone to "super-stalls", which claimed the lives of many test pilots. However, when training to recover from a super-stall, its pilots realized the plane was capable of rapidly lifting its nose to an almost vertical level, then recover after applying power and negative controls with minimal loss in altitude. This maneuver would later become known in Swedish as the "kort parad" (short parade in English), but to the rest of the world, it would receive the nickname of "Swedish Cobra".
