6 October 1918: During the Meuse-Argonne offensive of World War I, approximately 554 soldiers of the 77th “Metropolitan” Division advanced into the Argonne Forest with a French division on their left flank and the American 92nd Division to the right. They moved quickly, unaware that the flanking units were held up. Soon, they were far ahead of the Allied advance and became cut off behind the German lines. With higher ground to all sides, the elements of the 307th and 308th Infantry Regiments and 306th Machine Gun Battalion came under heavy attack by enemy infantry and artillery.

With their communications cut off, they were soon low on food and ammunition. The only water available was a nearby stream that was protected by German gunfire.

Major General Robert Alexander, commanding the 77th Division, requested that the 50th Aero Squadron, based at Remicourt, attempt to locate the cut-off unit and resupply them by air. Among the officers of the 50th participating in the search were First Lieutenant Harold Ernest (“Dad”) Goettler, the 1st Flight commander, and Second Lieutenant Erwin Russell Bleckley, flying an American-built Liberty-engined DH-4. On their first flight they flew their own aircraft, squadron number 2. Later in the day, after developed engine trouble, they used another crew’s .

Having been subjected on the first trip to violent fire from the enemy, they attempted on the second trip to come still lower in order to get the packages even more precisely on the designated spot.

The Airco DH.4 was a very successful airplane of World War I, designed by Geoffrey de Havilland. The DH.4 (DH-4 in American service) was a two-place, single-engine, two-bay biplane with fixed landing gear. The fuselage and wings were constructed of wood and covered with doped-fabric. The airplane was produced by several manufacturers in Europe and the United States. The DH-4 was 30 feet, 5 inches (9.271 meters) long with a wingspan of 42 feet, 8 inches (13.005 meters) and height of 10 feet, 6 inches (3.200 meters). The DH-4 had an empty weight of 2,391 pounds, (1,085 kilograms) and gross weight of 4,297 pounds (1,949 kilograms). Fuel capacity was 67 gallons (254 liters).

Army Air Service DH-4s were powered by Liberty 12 aircraft engines in place of the Rolls-Royce Eagle VII V-12 of the British-built DH.4 version. The L-12 was water-cooled, normally-aspirated, 1,649.34-cubic-inch-displacement (27.028 liter), single overhead cam (SOHC) 45° V-12 engine. It produced 408 horsepower at 1,800 r.p.m. The L-12 as a right-hand tractor, direct-drive engine and it turned turned a two-bladed fixed-pitch wooden propeller. The Liberty 12 was 67.375 inches (1.711 meters) long, 27.0 inches (0.686 meters) wide, and 41.5 inches (1.054 meters) high. It weighed 844 pounds (383 kilograms).

The Liberty 12 aircraft engine was designed by Jesse G. Vincent of the Packard Motor Car Company and Elbert J. Hall of the Hall-Scott Motor Company. This engine was produced by Ford Motor Company, as well as the Buick and Cadillac Divisions of General Motors, The Lincoln Motor Company (which was formed by Henry Leland, the former manager of Cadillac, specifically to manufacture these aircraft engines), Marmon Motor Car Company and the Packard Motor Car Company. Hall-Scott was too small to produce engines in the numbers required.

The DH-4 had a maximum speed of 124 miles per hour (200 kilometers per hour), service ceiling of 19,600 feet (5,974 meters) and range of 400 miles (644 kilometers).

Many DH-4s were rebuilt as DH-4Bs. These can be identified by the relocated pilot’s cockpit, which was moved aft, closer to the observer’s position. The an enlarged fuel tank was place ahead of the pilot’s cockpit. Following World War II, many were rebuilt with tubular metal frames for the fuselage, replacing the original wooden structure. These aircraft were redesignated DH-4M.

The prototype American DH-4, Dayton-Wright-built airplane, is in the collection of the Smithsonian Institution National Aviation and Space Museum.

This DH-4, serial number 32364, was assigned to the 50th Aero Squadron. The unit’s Dutch Girl insignia is painted on the fuselage along with the squadron number, 10. The name of the person standing by the airplane is not known. (San Diego Air & Space Museum Archives)

4 September 1922: First Lieutenant James H. (“Jimmy”) Doolittle, Air Service, United States Army, made the first transcontinental crossing of the United States in a single day when he flew a DH.4B-1-S single-engine biplane, Air Service Serial Number 22-353, from Pablo Beach, Florida, ¹ to Rockwell Field, San Diego, California, a distance of 2,106 miles (3,390 kilometers). He made one refueling stop at Kelly Field, San Antonio, Texas, which lasted 1 hour, 16 minutes. The total duration of the flight was 21 hours, 19 minutes.

Lieutenant Doolittle was awarded the Distinguished Flying Cross for “demonstrating the possibility of moving Air Corps units to any portion of the United States in less than 24 hours.”

The Airco DH.4 was a very successful airplane of World War I, designed by Geoffrey de Havilland. It was built by several manufacturers in Europe and the United States. The DH-4B was a rebuilt DH.4 with fuel capacity increased to 110 gallons (420 liters). The DH-4B was 30 feet, 6 inches (9.296 meters) long with a wingspan of 43 feet, 6 inches (13.259 meters) and height of 10 feet, 4 inches (3.150 meters). Loaded weight of the standard DH-4B was 3,557 pounds (1,613.4 kilograms).

In place of the Rolls-Royce Eagle VII V-12 of the British-built version, Army Air Service DH-4s were powered by a water-cooled, normally-aspirated, 1,649.336-cubic-inch-displacement (27.028 liter) Liberty L-12 single overhead cam (SOHC) 45° V-12 engine with a compression ratio of 5.4:1. The Liberty produced 408 horsepower at 1,800 r.p.m. The L-12 as a right-hand tractor, direct-drive engine. It turned turned a two-bladed fixed-pitch wooden propeller. The Liberty 12 was 5 feet, 7.375 inches (1.711 meters) long, 2 feet, 3.0 inches (0.686 meters) wide, and 3 feet, 5.5 inches (1.054 meters) high. It weighed 844 pounds (383 kilograms).

The Liberty L12 aircraft engine was designed by Jesse G. Vincent of the Packard Motor Car Company and Elbert J. Hall of the Hall-Scott Motor Company. This engine was produced by Ford Motor Company, as well as the Buick and Cadillac Divisions of General Motors, The Lincoln Motor Company (which was formed by Henry Leland, the former manager of Cadillac, specifically to manufacture these aircraft engines), Marmon Motor Car Company and Packard. Hall-Scott was too small to produce engines in the numbers required.

This same airplane, DH.4B-1-S, A.S. No. 22-353, was flown from the Gulf of Mexico to the Canadian border by Lieutenant H.G. Crocker, 26 May 1923.

Jimmy Doolittle was one of America’s foremost pioneering aviators. He set many records, won air races, tested and developed new flying equipment and techniques. He was a highly-educated military officer, having earned his Bachelor of Arts from the University of California Berkeley School of Mines, and M.S and D.Sc. degrees in Aeronautical Engineering from the Massachusetts Institute of Technology.

During World War II Colonel Doolittle planned and led the famous Halsey-Doolittle Raid against Japan, 18 April 1942, for which he was awarded the Medal of Honor. As a brigadier general he commanded Twelfth Air Force in North Africa. Promoted to major general, he was given command of the Fifteenth Air Force in the Mediterranean Theater. From 1943 until 1945, Lieutenant General Doolittle commanded Eighth Air Force. He was preparing his command to move against Japan, equipped with Boeing B-29 Superfortress bombers when World War II came to an end.

After the war, Lieutenant General Doolittle was placed on the inactive list. On 4 April 1985, by Act of Congress, James H. Doolittle was promoted to General.

General James Harold Doolittle is the only person to be awarded both the Medal of Honor and the Medal of Freedom. He died 27 September 1993 at the age of 96 years. He was buried at the Arlington National Cemetery, Arlington, Virginia.
