This educational HD video explains the history of German 88mm FLAK anti-aircraft technology evaluated by the United States Air Force in 1944. Totaling 15,000 defensive batteries, Germany usually deployed anti-aircraft batteries in rectangular formations using the infamous 88mm flak design in the largest numbers. In modern history, early flak batteries used optical range finders to estimate distances to targets but were later re-engineered with new radar technology to precisely estimate direction and range, and greatly increasing accuracy particularly at night. It took an estimated average 3,300 88mm shots to successfully bring down a high-altitude aircraft such as the Boeing B-17 airplane. This film has been restored at 1080p HD.
