The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting a Bronze Oak Leaf Cluster in lieu of a Second Award of the Distinguished Flying Cross to Lieutenant Colonel (Air Corps) John Dale Ryan (AFSN: AO-21117/ASN: 0-21117), United States Army Air Forces, for extraordinary achievement while participating in aerial flight as Pilot of a B-17 type aircraft of the FIFTEENTH Air Force. On 10 May 1944, Lieutenant Colonel Ryan led his group on an important bombing mission against a heavily defended enemy aircraft factory in Austria. Severe and adverse weather conditions were encountered en route to the target, through which Lieutenant Colonel Ryan brought his entire formation directly to the target. Despite intense and accurate enemy anti-aircraft fire, he led the group over the objective for a highly successful bombing run completely destroying the target. On the return trip he again brought his formation through adverse weather conditions for a safe landing at base without loss. By his outstanding leadership, sound judgment and devotion to duty, together with his exceptional professional skill as evidenced throughout over twenty-one successful missions against the enemy, Lieutenant Colonel Ryan has reflected great credit upon himself and the Armed Forces of the United States of America.
