"[12] Before the B-29's exclusive deployment to the Pacific Theater began, the United States Army Air Forces initiated a disinformation campaign through leaflets over the Third Reich early in 1944 that hinted at what sorts of American heavy bombers were likely to appear over Germany in the future.
Partly in conjunction with use of YB-29-BW 41-36393, the so-called Hobo Queen, one of the service test aircraft flown around several British airfields in early 1944, four-page German language Sternenbanner-headlined, American-published propaganda leaflets mentioning a "battle of annihilation against the Luftwaffe" (Vernichtungsschlacht gegen die Luftwaffe), dated to Leap Year Day in 1944, were dropped over the Reich,[16] with the intent to deceive the Germans into believing that the B-29 would be deployed to Europe.
