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 First Lieutenant (Air Corps) Harold J. Zweifel (ASN: 0-524669), United States Army Air Forces, for extraordinary achievement while participating as Pilot in more than six hundred hours of operational flight in transport aircraft from 7 September 1944 to 17 February 1945, over the dangerous and difficult Assam-China Air Routes, where enemy interception and attack was probable and expected. Flying at night as well as by day, at high altitudes over impassable mountainous terrain through areas characterized by extremely treacherous weather conditions necessitating long periods of operation on instruments, often encountering severe icing conditions and mechanical difficulties requiring courageous and superior performance of his duties. His heroic achievement in the face of the hazards and difficulties faced regularly and continuously with steadfast devotion to duty, reflects much credit on himself and the Army Air Forces of the United States.
