Reupload of a previously uploaded film with improved video & sound.
Public domain film from the US National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).
…The Air Service of 1925 numbered five airship companies, an airship service company, 32 tactical squadrons (eight pursuit, eight bombardment, two attack, and 14 observation), six school squadrons,[n 28] and 11 service squadrons. Half of the pursuit and bombardment squadrons and three each of the observation and service squadrons were based outside the continental United States…
The principal pursuit planes of the Air Service were the MB-3 (50 in inventory), the MB-3A (200 acquired 1920-23), and the Curtiss PW-8/P-1 Hawk (48 acquired in 1924-25). The only bomber ordered in quantity was the Martin NBS-1, the mass-produced version of the MB-2 bomber developed in 1920…
The United States Army Air Corps (USAAC) was a forerunner of the United States Air Force. Renamed from the Air Service on 2 July 1926, it was part of the United States Army and the predecessor of the United States Army Air Forces (USAAF), established in 1941. Although abolished as an organization in 1942, the Air Corps (AC) remained as a branch of the Army until 1947.
The Air Corps was renamed by the United States Congress largely as a compromise between advocates of a separate air arm and those of the Army high command who viewed the aviation arm as an auxiliary branch to support the ground forces. Although its members worked to promote the concept of airpower and an autonomous air force between 1926 and 1941, its primary purpose by Army policy remained support of ground forces rather than independent operations…
The 2nd Wing, activated in 1922 as part of the Air Service, remained the only wing organization in the new Air Corps until 1929, when it was redesignated the 2nd Bombardment Wing in anticipation of the activation of the 1st Bombardment Wing to provide a bombardment wing on each coast. The 1st Bomb Wing was activated in 1931…
In 1927 the Air Corps adopted a new color scheme for painting its aircraft, heretofore painted olive drab. The wings and tails of aircraft were painted chrome yellow, with the words “U.S. ARMY” displayed in large black lettering on the undersurface of the lower wings. Tail rudders were painted with a vertical dark blue band at the rudder hinge and 13 alternating red-and-white horizontal stripes trailing.
