WA 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens. It is widely used in optical engineering laboratory work to analyze and validate imaging systems such as microscopes, cameras and image scanners.
WOn 24 January 1963 a United States Air Force Boeing B-52C Stratofortress with nine crew members on board lost its vertical stabilizer due to buffeting stresses during turbulence at low altitude and crashed on Elephant Mountain in Piscataquis County, Maine, United States, six miles (9.7 km) from Greenville. The pilot and the navigator survived the accident.
WThe Aeronautical Division, Signal Corps (1907–1914) was the first heavier-than-air military aviation organization in history and the progenitor of the United States Air Force. A component of the U.S. Army Signal Corps, the Aeronautical Division procured the first powered military aircraft in 1909, created schools to train its aviators, and initiated a rating system for pilot qualifications. It organized and deployed the first permanent American aviation unit, the 1st Aero Squadron, in 1913. The Aeronautical Division trained 51 officers and 2 enlisted men as pilots, and incurred 13 fatalities in air crashes. During this period, the Aeronautical Division had 29 factory-built aircraft in its inventory, built a 30th from spare parts, and leased a civilian airplane for a short period in 1911.
WThe Air Force Historical Research Agency is the repository for United States Air Force historical documents. The Agency's collection, begun during World War II in Washington, D.C. and moved in 1949 to Maxwell Air Force Base, the site of Air University, to provide research facilities for professional military education students, the faculty, visiting scholars, and the general public.
WThe Air War Plans Division (AWPD) was an American military organization established to make long-term plans for war. Headed by Harold L. George, the unit was tasked in July 1941 to provide President Franklin D. Roosevelt with "overall production requirements required to defeat our potential enemies." The plans that were made at the AWPD eventually proved significant in the defeat of Nazi Germany.
WThe United States Army Air Service (USAAS) was the aerial warfare service component of the United States Army between 1918 and 1926 and a forerunner of the United States Air Force. It was established as an independent but temporary branch of the U.S. War Department during World War I by two executive orders of President Woodrow Wilson: on May 24, 1918, replacing the Aviation Section, Signal Corps as the nation's air force; and March 19, 1919, establishing a military Director of Air Service to control all aviation activities. Its life was extended for another year in July 1919, during which time Congress passed the legislation necessary to make it a permanent establishment. The National Defense Act of 1920 assigned the Air Service the status of "combatant arm of the line" of the United States Army with a major general in command.
WThe Aviation Section, Signal Corps, was the aerial warfare service of the United States from 1914 to 1918, and a direct statutory ancestor of the United States Air Force. It absorbed and replaced the Aeronautical Division, Signal Corps, and conducted the activities of Army aviation until its statutory responsibilities were suspended by President Woodrow Wilson in 1918. The Aviation Section organized the first squadrons of the aviation arm and conducted the first military operations by United States aviation on foreign soil.
WThe Bomber Mafia were a close-knit group of American military men who believed that long-range heavy bomber aircraft in large numbers were able to win a war. The derogatory term 'Bomber Mafia' was used before and after World War II by those in the military who did not share their belief, and who were frustrated by the insistence of the men that the heavy bomber should take a primary position in planning and funding.
WCivil Air Patrol (CAP) is the civilian auxiliary of the United States Air Force (USAF). It was created by Administrative Order 9 in December 1941, with Maj. Gen. John F. Curry as the first CAP national commander. The organization was originally formed to provide civilian air support to aid the war effort of World War II through border and coastal patrols, military training assistance, courier services and other activities. These efforts were recognized and, after the close of the war, Civil Air Patrol was transferred from the United States Army to the newly formed U.S. Air Force. Through the enactment of Public Law 79-476 by the U.S. Congress and signed by President Harry S. Truman, Civil Air Patrol was incorporated as a nonprofit organization of "volunteers and declared to be of a benevolent nature, never again to be involved in direct combat activities."
WOn 27 March 1999, during the NATO bombing of Yugoslavia, a Yugoslav army unit shot down an F-117 Nighthawk stealth aircraft of the United States Air Force by firing a S-125 Neva/Pechora surface-to-air missile. The pilot ejected safely and was rescued by allied search and rescue forces.
WThe Fairy Lochs is a recent English name for Na Lochan Sgeireach and are a small group of freshwater lochans approximately 2 miles (3 km) south-east of the village of Badachro near Gairloch in Wester Ross, Scottish Highlands. The lochans have become known as the 'Fairy Lochs' due to their proximity to 'Sìthean Mòr' which translates as 'Big Fairy Hill'.
WThe first aerial circumnavigation of the world was completed in 1924 by four aviators from an eight-man team of the United States Army Air Service, the precursor of the United States Air Force. The 175-day journey covered over 26,345 miles (42,398 km). The team generally traveled east to west, around the northern-Pacific Rim, through to South Asia and Europe and back to the United States. Airmen Lowell H. Smith and Leslie P. Arnold, and Erik H. Nelson and John Harding Jr. made the trip in two single-engined open-cockpit Douglas World Cruisers (DWC) configured as floatplanes for most of the journey. Four more flyers in two additional DWC began the journey but their aircraft crashed or were forced down. All airmen survived.
WThe Heavy Press Program was a Cold War-era program of the United States Air Force to build the largest forging presses and extrusion presses in the world. These machines greatly enhanced the US defense industry's capacity to forge large complex components out of light alloys, such as magnesium and aluminium. The program began in 1950 and concluded in 1957 after construction of four forging presses and six extruders, at an overall cost of $279 million. Eight of them are still in operation today, manufacturing structural parts for military and commercial aircraft. They still hold the records for size in North America, though they have since been surpassed by presses in Japan, France, Russia and China.
WThe National Museum of the United States Air Force is the official museum of the United States Air Force located at Wright-Patterson Air Force Base, 6 miles (9.7 km) northeast of Dayton, Ohio. The NMUSAF is the oldest and largest military aviation museum in the world, with more than 360 aircraft and missiles on display. The museum draws about a million visitors each year, making it one of the most frequently visited tourist attractions in Ohio.
WThe "Revolt of the Admirals" was a policy and funding dispute within the United States government during the Cold War in 1949, involving a number of retired and active-duty United States Navy admirals. These included serving officers Admiral Louis E. Denfeld, Chief of Naval Operations, and Vice Admiral Gerald F. Bogan, as well as Fleet Admirals Chester Nimitz and William Halsey, senior officers in World War II.
