Alert and Training would be the experienced instructors as well as those students that had reached "a reasonably satisfactory standard of training". Few training schools were close to likely invasion areas and moving them seemed unwise in the chaos of an invasion, when closer airfields would have been bombed and were busy servicing their operational squadrons. It was decided to base four flights of 5–6 basic trainer aircraft to Army Cooperation, Coastal and Bomber command bases, two flights at first and two more if the base commander decided that they could be accommodated. The air bases were widely spread and no swarms of Banquet aircraft would have descended on the landing beaches, the main effort would be by conventional Bomber Command squadrons. Army Cooperation Command was instructed that, When to implement the Banquet scheme was kept open; if a German landing occurred away from the concentrations of the British army, such as Scotland, the scheme would be put into effect straight away but if a landing came where expected, the aircraft would be used as a last resort, dependent on how swiftly the situation deteriorated. Banquet Light Among the Banquet plans was Banquet Light which would see the formation of striking forces composed of De Havilland Tiger Moth biplanes and other light aircraft of Elementary Flying Training Schools. De Havilland put forward plans for converting the Tiger Moth into a bomber by equipping it with eight bomb racks beneath the rear cockpit. As an alternative, the bomb-racks could be installed four on each side under the lower planes, which would avoid trimming difficulties. The racks had been designed for the military version of the de Havilland Dragons supplied to Iraq eight years previously. Trials were conducted at Hatfield by Major Hereward de Havilland and at the Aeroplane and Armament Experimental Establishment at Boscombe Down and the machines earned a satisfactory report. Tests were also carried out with a Tiger Moth carrying a bomb. Modification of the relatively small number of Miles Magister trainers were also attempted but this proved troublesome and Banquet Light mostly used Tiger Moths. The Banquet Light strike force would be used for Army co-operation, bombing concentrations of airborne troops or soldiers landing on the beaches. The two-seater Tiger Moth bombers should be flown solo into an attack at low altitude until the enemy was identified, climb to and dive to to release the bombs. Most of
