The 2º/5º GAV Esquadrão Joker was activated in 1953 at Natal Air Base, initially focused on training bomber pilots and later fighter pilots. It operated several historic aircraft, such as the Republic P-47D Thunderbolt and the North American B-25J Mitchell. After some restructurings, it returned to operating as a fighter unit in 1983, adopting the radio call sign "Joker." Today, the squadron trains Brazilian Air Force fighter pilots using the modern Embraer A-29 Super Tucano.
The emblem features an ostrich teaching a penguin the art of fighter aviation. The ostrich represents the instructor, while the penguin symbolizes the trainee. This depiction highlights the continuity of traditions and the transfer of knowledge between generations of aviators.
A fun fact: The ostrich became a symbol for Brazilian pilots in World War II for an interesting reason. During their training in the U.S., many didn’t speak English and always stuck together — like a flock of ostriches. They also had to face exotic American cuisine, with unusual combinations like beans with sugar, pineapple soup, and powdered eggs — flavors that were quite strange to the Brazilian palate. This led to the joke that only someone with an “ostrich stomach” could handle it. And that’s how the mascot came to be.
