The third Friday in September is recognized as POW/MIA Day, a time to remember the sacrifices of prisoners of war (POW) and servicemembers who are missing in action (MIA). Until 1979, there was no formal recognition day set aside for these important men and women in uniform.
World War II had been over for two years and the Korean War lay three years ahead when the Air Force ended a 40-year association with the U.S. Army to become a separate service. The U.S. Air Force thus entered a new era in which airpower became firmly established as a major element of the nation's defense and one of its chief hopes for deterring war. The Department of the Air Force was created when President Harry S Truman signed the National Security Act of 1947.
On September 17, 1787, the Founding Fathers signed the U.S. Constitution. For the past 225 years, the Constitution has served as the supreme law of the land. The Constitution, along with the Bill of Rights and other amendments, define our government and guarantee our rights. Each year, on September 17, Americans celebrate Constitution Day and Citizenship Day. In addition, September 17-23 is also recognized as Constitution Week. During this time, USCIS encourages Americans to reflect on the rights and responsibilities of citizenship and what it means to be a U.S. citizen.
