While stationed at McCook, he planned the first transpacific flight to Hawaii, then using his flight plan, flew the Bird of Paradise to Hawaii with 1st Lt. Lester J. Maitland on June 28–29, 1927, for which they won the Mackay Trophy.[1] Resuming his work at Wright Field, Hegenberger developed the first blind flying landing system, (using non-directional and marker beacons) and on May 9, 1932, made the first complete solo blind flight from take-off to landing, for which he was presented the 1934 Collier Trophy on July 22, 1935, by President Franklin D. Roosevelt.[4][5]

He joined the 30th Bombardment Squadron at Rockwell Field, San Diego, California, in August 1935, and was made squadron commander in October. He later moved with this unit to March Field, California, where he served until August 1937. Hegenberger was a student at the Air Corps Tactical School at Maxwell Field, Alabama from September 1938 to June 1939. He then moved on to Fort Leavenworth, Kansas, where he completed the Command and General Staff School in June 1939.[3]

Hegenberger was assigned to Hickam Field, Hawaii, as operations officer of the 5th Bombardment Group in July 1939, and the following February became operations officer of the 18th Wing at Hickam Field. He moved to Fort Shafter, Hawaii, in November 1940 to become assistant chief of staff for operations of the Hawaiian Air Force, and in April 1941, was named commanding officer of the 11th Bombardment Group at Hickam Field.[3]

Hegenberger began World War II in command of the 18th Bombardment Wing at Hickam Field, and in January became chief of staff of the VII Bomber Command. From August to October 1942, he was assistant chief of staff for operations of the Second Air Force, and commanding officer of its II Bomber Command at Fort George Wright, Washington. In October 1942, he organized the 21st Bombardment Wing, a staging organization for heavy bombardment crews headed overseas, at Smoky Hill Army Air Base, Salina, Kansas, and commanded in until January 1944. In May 1943 he moved the wing to Topeka Army Air Base, Kansas. In January 1944, he was reassigned to Headquarters, Second Air Force, now at Colorado Springs, Colorado, as chief of staff. In January 1945, he was named chief of staff of the Fourteenth Air Force in the China Theater of Operations, and in August became commander of the Tenth Air Force in the same theater.[3]

Returning to the United States in December 1945, he was assigned to Headquarters, Army Air Forces, for duty with the Officers Selection Committee. In July 1946, he went to Pacific Air Command (PACUSA) headquarters in Tokyo, Japan, and two months later became commanding general of the 1st Air Division on Okinawa.

On 1 July 1948, a reorganization moved the organization to the office of the Deputy Chief of Staff—Operations, and Hegenberger succeeded Kepner as chief of Special Weapons Group. In August 1948, under the Assistant For Atomic Energy, his position was retitled Chief, 1009th Special Weapons Squadron.[3][6]
