Signal Corps Dirigible No. 1
Signal Corps Dirigible No. 1 was the first powered aircraft ordered for the Signal Corps by the Aeronautical Division of the United States Army. The purchase of SC-1, a dirigible designed by Thomas Scott Baldwin was the result of urgings by Chief Signal Officer Brigadier General James Allen. After seeing Baldwin demonstrate a dirigible at the St. Louis air meet in 1907, Allen had urged the U.S. Army to buy a dirigible as many European armies had dirigibles by the turn of the century.〔Baldwin Dirigible: U.S. Army\'s First Airship.

On 5 August 1908, the Army tested SC-1 at Fort Myer, Virginia. The craft fell short of a 2-hour, 20 mph objective to meet a $8,000 per unit award. The Army formally accepted the craft as Signal Corps Dirigible No. 1 paying $5,737.50. On 28 Aug. 1908 Lieutenants Frank Lahm, Thomas Selfridge and Benjamin Foulois were taught to fly the craft.〔
After Second Lieutenant John G Winter Jr of the 6th Cavalry was assigned to duty in the Aeronautical Division, the balloon detachment was transferred to Fort Omaha, Nebraska.
On 26 May, pilot Lieutenant Lahm and Lieutenant Foulois made a flight in SC-1 at Fort Omaha and manoeuvred the craft at will. SC-1 remained there until scrapped in 1912. The Army did not purchase another dirigible until after World War I.〔
