WORLD WAR II ANTI-AIRCRAFT GUN DOCUMENTARY " ACK ACK " 77954

Support Our Channel : / periscopefilm
This WWII Ministry of Information film shows the Ack Ack gun crew using their mobile gun. The narrator speaks about the diverse backgrounds of the recruits, and discusses how the gun (most likely a 40mm Bofors cannon) can fire a shell up to 30,000 feet. A height finder and a predictor are used to come up with a firing solution to hit incoming aircraft. The commentator also notes that enemy planes often fly a zig-zag or other evasive course to avoid being hit, but this can also have a positive outcome in that it prevents bombers from making accurate attacks. A command post is seen at the 3:30 mark, with enemy and friendly planes being tracked at all times. As nighttime approaches, radar is also used to spot enemy aircraft.
The Kerrison Predictor was one of the first fully automated anti-aircraft fire-control systems. The predictor could aim a gun at an aircraft based on simple inputs like the observed speed and the angle to the target. Such devices had been used on ships for gunnery control for some time, and versions such as the Vickers Predictor were available for larger anti-aircraft guns intended to be used against high-altitude bombers, but the Kerrison's electromechanical analog computer was the first to be fast enough to be used in the demanding high-speed low-altitude role, which involved very short engagement times and high angular rates.
Anti-aircraft warfare or counter-air defence is defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action." They include ground-and air-based weapon systems, associated sensor systems, command and control arrangements and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries the main effort has tended to be 'homeland defence'. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence as are initiatives to adapt air defence to the task of intercepting any projectile in flight.
In some countries, such as Britain and Germany during the Second World War, the Soviet Union and NATO's Allied Command Europe, ground based air defence and air defence aircraft have been under integrated command and control. However, while overall air defence may be for homeland defence including military facilities, forces in the field, wherever they are, invariably deploy their own air defence capability if there is an air threat. A surface-based air defence capability can also be deployed offensively to deny the use of airspace to an opponent.

    It was Hitler’s intention that he get the U.K. on his side to begin with, as he considered the English, specifically, to be “kin” to the “German/Aryan.” But, Hitler was just a bit touched in the head when it came to many things he believed. He just happened to come along at what was precisely the wrong time, Politically, for the Government of Germany to effectively oppose his Populist and Revanchist message, which is a type of political pandering that remains pretty effective even when Social and Economic Conditions aren’t “horrible,” as was the case in the late Weimar Era. The Political-divisions in Germany resulted in Hitler’s rather rapid rise to power. And even though most of the population didn’t explicitly support him, Herr Hitler did win up receiving more-and-more support as conditions improved, and due to the rather unfortunate effect within Democracies of a population tending to support whoever is in power, out of the mistaken belief that doing so will somehow make them “more influential” WITH said Government (or that it will “protect” them from any “bad policies” of that government). Populism remains one of the most powerful opponents of Liberal/Western Democracy, even today. And the tendency of Populism to lean heavily toward Nationalism still produces the exact same kind of scapegoating of “The Other” that occurred in the Third Reich. The Targets of Populists identified as “The Other” just change over time. To the Populist-Right, the “Other” becomes minorities and immigrants (which often still includes “Jews,” as they seem to be a part of all Conspiracies in some way or another). And to Populist-Leftists “The Other” is the “Wealthy” or large Corporations (and, again, the “Jews” usually get sucked into these Conspiracies as well, given that many banks are still controlled by Jewish Families - or at least still connected to them, along with several very prominent Billionaires who are Jewish... “OBVIOUSLY” they are part of some super-secret cabal oppressing people across the globe). And thus you often get strange alliances and opposition due to Populist Regimes coming to power. Prior to the crash of 1929, Germany was seen as an emerging powerhouse of Global Progress, Industry, and the Arts... And then History occurred.
