During WWII Bombers modified their tactics and equipment to mitigate the effects of German FLAK on the bomber loss rates. One of the most effective tactic was for the bombers to saturate the target area by reduction in Trail. Trail is the distance between formations. Analysis and case studies showed, this saturation tactic as the most effective method to reduce bomber losses from FLAK. The video will address US saturation tactics, German response and review the results of a case study where bomber losses were reduced by 50% by reduction in trail distances were adopted.
