These militia units trace their lineage into the 17th century and through the Revolutionary War. Militia involvement in the Revolutionary War marked a rebirth of the militia under the "United Colonies," eventually the United States. The colonists resented and feared a standing military force following the abuses of the British Regular Army. Given that history, the young nation's citizens understandably feared abuses of military power." National Guard

While Air Force officers have made significant contributions to this success, so too has the enlisted force...In 1907, just four years after Wilber and Orville Wright took flight at Kitty Hawk, North Carolina, the US Air Force of today first established its military roots as the Aviation Section of the US Army Signal Corps. The division was created to take “charge of all matters pertaining to military ballooning, air machines, and all kindred subjects,” according to notations by the Air Force Historical Research Agency. The Aviation Section was built up during modern aviation’s early inception and initially only had stewardship over 10 hot air balloons. A year later, the Army began flight testing airplanes at Fort Myer, Virginia. One pilot, Lt. Thomas E. Selfridge, died in a plane crash during the testing stage, but the early aircraft, a Wright Model A, was improved upon. Subsequently, “Airplane No. 1” was adopted into the Army’s aerial arsenal on 2 August 1909." Air Force
