United States Air Force
The U.S. War Department created the first antecedent of the U.S. Air Force, as a part of the U.S. Army, on 1 August 1907, which through a succession of changes of organization, titles, and missions advanced toward eventual independence 40 years later. In World War II, almost 68,000 U.S. airmen died helping to win the war, with only the infantry suffering more casualties. In practice, the U.S. Army Air Forces (USAAF) was virtually independent of the Army during World War II, and in virtually all ways functioned as an independent service branch, but airmen still pressed for formal independence. The National Security Act of 1947 was signed on 26 July 1947 by President Harry S Truman, which established the Department of the Air Force, but it was not until 18 September 1947, when the first secretary of the Air Force, W. Stuart Symington, was sworn into office that the Air Force was officially formed as an independent service branch.
Hispanics in the United States Air Force
Hispanics in the United States Air Force can trace their tradition of service back to the United States Army Air Forces (USAAF), the military aviation arm of the United States Army during and immediately after World War II. The USAAF was the predecessor of the United States Air Force, which was formed as a separate branch of the military on September 18, 1947, under the National Security Act of 1947. In the U.S., the term "Hispanic" categorizes any citizen or resident of the United States, of any racial background, of any country, and of any religion, who has at least one ancestor from the people of Spain or is of non-Hispanic origin but has an ancestor from Mexico, Puerto Rico, Cuba, Central or South America, or some other Hispanic origin. The three largest Hispanic groups in the United States are the Mexican-Americans, Puerto Ricans, and Cubans. According to the U.S. Census Bureau the estimated Hispanic population of the United States is over 50 million, or 16% of the U.S. population, and Hispanics are the nation's largest ethnic minority. The 2010 U.S. Census estimate of over 50 million Hispanics in the U.S. does "not" include the 3.9 million residents of Puerto Rico, thereby making the people of Hispanic origin the nation's largest ethnic or race minority as of July 1, 2005.
