It has been estimated that 70 bombers came over London one day recently, while 30 more were identified near the coast. Both A.A. guns and fighter aircraft were in action in the London area, but for the most part the raiders kept so high that the searchlights could not reach them.
Unless the beams can illuminate a raider there is nothing for the A.A. guns to fire at, while it is almost impossible for a fighter pilot to spot a slím bomber in the darkness when both are moving at something -like 250 m.p.h. and with the pilot's eyesight somewhat dimmed by the glass of his windscreen. It is not considered good tactics to fire A.A. guns unless a target is in view, for the shell fragments have to come down and are a real danger t A.R.P. Workers.
