One of the most effective demonstrations of air supremacy by the Western Allies over Europe occurred in early 1944, when Lieutenant General Jimmy Doolittle, who took command of the US 8th Air Force in January 1944, only a few months later “released” the building force of P-51 Mustangs from their intended mission to closely escort the 8th Air Force’s heavy bombers, after getting help from British aviators in selecting the best available aircraft types for the task. A 2014 WHO worldwide survey on maternal and perinatal health found a statistically significant association between low birth weights (LBW) and increased levels of exposure to PM2.5. His aircraft had limited effect on Britain for a variety of reasons, but low payload was among them. On December 27, 1938, the United States had initiated the Civilian Pilot Training Program to vastly increase the number of ostensibly “civilian” American pilots, but this program also had the eventual effect of providing a large flight-ready force of trained pilots for future military action if the need arose.

Although largely a forgotten war by Western standards, the significance and impact of the airwar between China and the Empire of Japan cannot be denied; it was the best opportunity for the Western air powers to learn about the might of Japanese aerial and naval military technological prowess, as the West were yet in for a dangerous realization of Japanese air prowess by the end of 1941, when the Empire of Japan expanded into the Pacific. Most new Japanese installations in the Pacific were ramshackle affairs with poor siting, poor drainage, scant protection, and narrow, bumpy runways. The Chinese Air Force equipped with a maximum of only about 300 imported operational combat aircraft at any given time, was stretched thin over a massive area of the northern, eastern, and southern fronts against approximately 1,000 operational combat aircraft of the Imperial Japanese forces supported by their own robust and rapidly developing aviation industry. A top-level Luftwaffe general, Walther Wever, had tried to make some form of strategic bombing capability a priority for the newly formed Luftwaffe through 1935 and into 1936, but his untimely death in June 1936 ended any hopes of developing such a force of long-range “heavies” possible, as his Ural bomber program for such four-engined aircraft, comparable to what the United States was already pioneering, literally died with him.

Early in the war, the Luftwaffe had excellent tactical aviation, but when it faced Britain’s integrated air defence system, the medium bombers actually designed, produced, and deployed to combat – meant to include the Schnellbomber high-speed mediums, and their intended heavier warload successors, the Bomber B design competition competitors-did not have the numbers or bomb load to do major damage of the sort the RAF and USAAF inflicted on German cities. The U.S. Navy’s “Bat” unpowered anti-ship ordnance was based around the same half-ton HE bomb as the Azon, but with the same bomb contained within a much more aerodynamic airframe, and used a fully autonomous onboard radar guidance system to control its flightpath, rather than an external source of control for the Azon. Both the Fritz X and the unarmored, rocket-boosted Henschel Hs 293 guided glide bomb were used successfully against Allied shipping during the Allied invasion of Italy following Italy’s capitulation to the Allies earlier in September 1943. Both weapons used the Kehl-Strasbourg radio control link: a joystick-equipped Funkgerät FuG 203 Kehl transmitter in a deploying aircraft, with the corresponding FuG 230 Straßburg receiver in the ordnance for guidance.

On the whole, however, the secret weapons were still another case of too little too late. However, avoid harsh chemical drain cleaners, which can damage pipes. However, the sight of a senior colleague killed by error was unnerving, and after the completion of operation Cobra, Army generals were so reluctant to risk “friendly fire” casualties that they often passed over excellent attack opportunities that would be possible only with air support. The airwar over China were the largest air battles fought since the Great War, involving the first prolonged and massed-deployments of aircraft carriers in support of expeditionary forces, extensive close-air support and air-interdiction strikes, significant use of airpower in the attacks against naval assets, and much of the technological and operational transitioning from the latest biplane fighter designs to the modern monoplane fighter designs. Republic of China Air Force had integrated various former-warlord air force men and machines, as well as overseas-Chinese volunteer aviators into the nominally Nationalist Air Force of China, and coordinating with the Second United Front of the National Revolutionary Army (NRA) and People’s Liberation Army (PLA), engaging in massive air-battles, close-air support operations, air-interdiction strikes, facing indiscriminate terror-bombing campaigns against all manners of civilian targets inflicted by the Imperial Japanese Army Air Service and the Imperial Japanese Navy Air Service.
