Here's a leaflet which was distributed over Germany and Poland, apparently during the year 1944 (as it refers to the drop tanks which would have been regular equipment aboard the P-51 Mustang long-range escort fighters then being fielded by the 8th Air Force), by the National Socialist government then in power within that area, which leaflet appears as follows: http://upload.wikimedia.org/wikipedia/en/7/72/V-2_Leaflet_testsitearea.jpg [Broken] And translates (primarily from the German, as my German is much better than my Polish), as follows: [In Polish] NOTICE! [In German] Not a bomb! Report immediately to the nearest police station or military airfield! ATTENTION! FUEL CONTAINER! *** Further, the Polish "To nie bomba!" appears to be the same phrase as the Russian "Eto ne bomba!", or "This is not a bomb!" (once again, my Russian is mush better than my Polish, so gimme a break, hey!). Finally, the Polish "MATERIAL PE(n)DNY!" means: "PROPELLANT MATERIAL!", or "FUEL!".
