BOMB LOAD 6. The bomb load carried is likely to average 1½ 2 tons per aircraft, the Me. 262 carrying up to 2000 lbs. EFFICIENCY OF ATTACK 7. A high proportion of the aircraft despatched would probably fail to reach the target area, no concentration would be achieved, and the attacks would not be pressed home. If the black-out were lifted concentration would be more effective. AREAS OF ATTACK 8. In view of the fighter defences of this country and the general inefficiency of the German Air Force attacks would probably be confined to the area south and east of the line Humber to Portsmouth.
