Explanation

Jagdgeschwader 1 (JG 1) was a German unit of fighter jets operating during World War I. It was originally formed of four Jastas (fighter squadrons) and came under the leadership of Manfred von Richthofen (the Red Baron) in June 1917. JG 1 became known as the "Flying Circus" because the squadron's jets were painted in clear, marked colours that made them easy to identify during battles.
