Above the Clouds!: Pointblank

On June 14th, 1943, the Combined Chiefs of Staff issued the Pointblank directive, which authorized the initiation of Operation Pointblank, the code name for the primary portion of the Allied Combined Bomber Offensive intended to cripple or destroy the German aircraft fighter strength, thus drawing it away from frontline operations and ensuring it would not be an obstacle to the invasion of Northwest Europe. Pointblank provides the Aircraft Performance Displays (APDs) required to fight the air engagements over Western Europe during 1943-1945. —description from the publisher
