TABLE 8 VISUAL AND RADAR BOMBING ACCURACIES

We consider that the proficiency of Long Range Aviation crews is such that they can, in training but under adverse conditions, navigate to an assigned target and bomb with the accuracies shown in the table below. The figures given would be degraded under combat conditions, and would also be degraded by the use of certain techniques for delivery of high-yield nuclear weapons, such as parachute drops.
