An aerial view of a German airfield during World War II, with a sunny sky adorned with contrails from U.S. B-17 bomb aircraft. At an altitude of 30,000 feet, 15 accurate, authentic true silhouettes of Boeing B-17 bomb aircraft are visible against the backdrop of scattered clouds. In the foreground, a 3-meter-diameter small, smooth flying saucer, camouflaged in mid-green and without markings or protrusions, hovers above the airfield. The saucer's smooth, 1-meter-high black dome contrasts with the historical setting. better Boeing B-17 aircraft, "Brandis Fliegerhorst"
