The QB-17 was a remote piloted drone aircraft initially used in the Bikini atomic bomb testes to check the effects of the nuclear blast on aircraft's flying characteristics and equipment. Later, in the 1950s, QB-17s were used as targets for Air Defense Command gunnery meets, and in the testing of a new generation of air to air missiles such as the Sidewinder. QB-17s were some of the most colorful aircraft in the Air Force, painted in Yellow with Black stripes, which sometimes covered the entire aircraft. Controller aircraft for the QB-17 drones were designated DB-17.

The history and variants of the B-17 would remain incomplete if one embezzled her exciting secret uses under the I./KG 200 of the German Luftwaffe. The B-17 were the most important spoils pattern of this group with which she carried out numerous long range missions under the assumed name Dornier Do 200, mostly in the G version. These machines operated in risky missions over all of Europe of Norway via Jordan up to the desert in the west of North Africa. The Germans aimed thus not at all primarily at a deception of the Allies but these machines were simply for the respective purpose suited better than every other German planes!
