Posting these here for commentary before bringing them to the main thread...
13: Universal Pod Mount. Design a mounting point for various removable pods so that a vehicle can quickly change its specifications by mounting a suitable pod. It should have a redundant release mechanism, the capacity to feed at least 5 different signals to an attached pod, and the ability for a pod to feed fuel to the vehicle. Design versions for pods of 20kg, 50kg, 200kg, and 500kg. Build a 50kg rocket pod designed to provide 2 minutes of additional propulsion to an aeroplane to test the system.
14: People's Beacon Carrier. Base it on Radar Airship but dedicated to aircraft docking. Attempt to integrate a pair of underside rails for receiving aircraft at higher speeds, a crane system for rapidly retrieving aircraft from the rails, a maintenance bay for aircraft, an aeroplane mounting system that would allow pilots to get from quarters to cockpits in under 2 minutes with no appreciable risk of plummeting to their untimely doom. It should also be possible to load bombs and such onto aircraft without transferring them to the maintenance bay. The rails should be reinforced around the regions most likely to be damaged and have a guide kite dragging behind it to better illustrate its position to approaching aeroplanes. The rail should also possess a slight incline to slow docking craft and one-way notches to prevent craft from sliding backwards. The airship itself should possess additional engines to better match the flight of relatively high-speed aircraft.
15: Plummet fighter. An aeroplane designed to operate with the P.B.C. Airship above. It should have a retractable over-head sled for docking with rails and a skid-plate for ground landings. Ideally it should possess great manoeuvrability, a high operational ceiling, low minimum speed, and special attention should be given to insuring that it can recover from stalls, as it will be launched by being dropped... Ideally its weight will be under 2000 kg though it should be armed with at least a pair of Patriotisms, ideally GVS-14s. It should also have two mounts for pods.
16: Descent bomber. As the Plummet above, but with a single forward Patriotism and a single rear gunner position with a Patriotism, the ability to carry a single torpedo or a similar weight of depth-charges or conventional bombs, and no need for manoeuvrability.
