U.S. Army Air Service Action 1925 Gunnery Bombing Blimp DH-4 Crop Duster National Archives NARA

Did the U.S. Army have blimps too? Take a look. Did World War I deHavilland DH-4 biplanes dust crops in the 1920s? Yes; it is in this 100-year-old film. The celebrated air races of the 1920s, like the Pulitzer and Schneider trophy events depicted in this footage, did their part to improve the speed and reliability of aircraft in the post-World War I era of rapid aviation growth. The races also bore witness to those advances, showcasing them to an enthusiastic public. The U.S. Army and U.S. Navy fielded air race teams in these events. The Army's helium-filled RS-1 semi-rigid airship was built by Goodyear and assembled in the huge airship hangar constructed at Scott Field in Illinois. This footage seems to be fudging a bit on the 1925 date, since first flight of the RS-1 took place in January 1926. Power at this time was provided by four Liberty engines. Two engines used a common transmission to turn one propeller; both propellers provided propulsion. This changed in 1927 to only a pair of Packard engines resulting in less weight and hence greater range. As seen in this film, the RS-1 with Liberty engines had a range of 1,722 miles. The Packard configuration boasted a range of 2,588 miles. Weakness in the blunt nose of the RS-1 caused crews to diminish speeds from 70 miles an hour to a maximum of 50. The RS-1 was conceived as a research vehicle. The RS-1 could carry 3,500 pounds of bombs. With the demise of Army airship operations in 1937, the huge hangar at Scott was torn down the following year. The Ruggles Orientator was a multi-axis cockpit simulator dating back to 1917. It could serve both as a selection tool to weed out some student pilot candidates, as well as a training device for successful applicants. Lieutenant Doolittle showed off the new Curtiss P-1 pursuit for the Air Service camera. The P-1 led to a series of experimental and production versions, culminating in the P-6E. The P-1 shown flew in the 160s; the ultimate P-6E could hit a top speed of 198 miles an hour. Air Service DeHavilland DH-4s were fitted with a hopper in the observer's station behind the pilot, from which powdered pesticides could be dispensed. Some DH-4B-models were given the nomenclature DH-4BD to signify their use as dusters. The Cox-Klemin Corporation built two XA-1 ambulance aircraft for the Army Air Service, first flying in 1923. A crew of two, plus two litter patients, could be carried. A 420-horsepower Liberty engine powered the XA-1. The XA-1s performed real-world ambulance missions. They were retired from the Air Service in 1932. This footage depicts the Army ship bombing tests of 1921. That looks like the USS Alabama under a spectacular phosphorous bomb explosion.
