Hawker P.1121 Staff having been unable to understand the concept of the multi-purpose functionality of the aircraft, which would become commonplace on later aircraft. While seeking a new project to take the place of the P.1121, Camm soon began work upon another new and radical aircraft design, designated as the Hawker Siddeley P.1127. The P.1127 would become the Hawker Siddeley Harrier, the first effective vertical take-off and landing (VTOL) combat aircraft. The Hawker P.1121 was envisioned as being one of the first British-built supersonic fighter aircraft, being projected to be capable of speeds of up to Mach 2.5. It was to have
Nord CT41 signature. Two types were produced, the CT.41A for high-altitude use, and the CT.41B for low-altitude training. If the drone was not shot down, recovery was via parachute. The CT.41 began test flights during 1959, with production starting later that year; 62 aircraft were constructed for use by the French Air Force. They had only a brief service life before being retired due to being too fast to provide practical training for interceptor pilots. Hawker Siddley acquired a manufacturing license for the type in November 1960. Six were acquired by Bell Aircraft for evaluation by the United States Navy; Bell also
