Hawker Siddeley Harrier single lever added in the cockpit. For horizontal flight, the nozzles are directed rearwards by shifting the lever to the forward position; for short or vertical takeoffs and landings, the lever is pulled back to point the nozzles downwards. The Harrier has two control elements not found in conventional fixed-wing aircraft: the thrust vector and the reaction control system. The thrust vector refers to the slant of the four engine nozzles and can be set between 0° (horizontal, pointing directly backwards) and 98° (pointing down and slightly forwards). The 90° vector is normally deployed for VTOL manoeuvring. The reaction control
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
