Yes, There was an Aerial Refueling in 1929
During the first week of January, 1929, the “who’s who” of Army Air Corps pioneers showed up to take a whack at refueling. Using an aircraft named the Question Mark, Major Carl A. Spatz (later spelled Spaatz), Captain Ira C. Eaker, Lieutenant Elwood Quesada, Lieutenant Harry A. Halverson and crewman Staff Sergeant Roy W. Hooe, flew the Fokker C-2 high winged monoplane, with two 96-gallon wing tanks, for a total of 150 hours and 40 minutes between Santa Monica and San Diego, California. While in the air, two Douglas C‑1 bi-planes with 150-gallon tanks refueled the Question Mark over the seven days of flying. This was all accomplished with ground, hand and flashlight signals as radios during 1929 were too heavy and unreliable. As historic and record breaking as the Question Mark refueling was, the U.S. Army was not impressed enough to provide funding. The Army Air Corps air refueling, once again, fell to the wayside.
