The Army Air Corps was periodically responsible for delivering air mail since the inception of air mail service. Its responsibilities were usually on an emergency or experimental basis.
Following is an Army Air Mail first flight cover of February 19, 1934, from Washington, D.C., to Colorado Springs. President Franklin D. Roosevelt declared an emergency and implemented the Army Air Mail Service on this date, citing possible corruption and collusion in the awarding of air mail contracts among private carriers. He canceled all existing air mail contracts and handed over responsibilities to the Army Air Corps. Contract air mail service was restored on June 1, 1934.
