The Horten H.IV was a German tailless flying wing glider in which the pilot lay in a prone position to reduce the frontal area, and hence drag. It was designed by Reimar and Walter Horten in Göttingen. Four were built between 1941 and 1943. They were flown in a number of unofficial competitions in Germany during World War II. After the war the flying examples were transported to the United Kingdom and the United States where several contest successes were achieved.
Northrop XB-35 "Flying Wing" - The Northrop XB-35 and YB-35 were experimental heavy bomber aircraft developed for the United States Army Air Forces during and shortly after World War II by the Northrop Corporation. It used the radical and potentially very efficient flying wing design, in which the tail section and fuselage are eliminated and all payload is carried in a thick wing.
Germany's Horten IX V2 ... the world's first turbojet-powered flying wing is prepared for flight tests somewhere in Germany in January 1945. Never progressing beyond the experimental stage, it was nevertheless far advanced beyond anything the allies had considered, even into the realm of radar deflecting stealth technology.
Like butterflies, different species of fruit flies decorate their wings with a great diversity of spots and patterns. Digging deep into a single gene that produce pigmentation in the flies, a group led by UW-Madison biologist Sean Carroll has found the molecular switches that control where the pigmentation is deployed. The finding explains how common genes can be controlled to produce the seemingly endless array of patterns, decoration and body architecture found in animals.
The Northrop YB-49 was a prototype jet-powered heavy bomber aircraft developed shortly after World War II. Intended for service with the U.S. Air Force, featured a flying wing design. It was a jet-powered.The two YB-49s actually built were both converted YB-35 test aircraft. The YB-49 never entered production, being passed over in favor of the more conventional Convair B-36 Peacemaker piston-driven design. First flight 21 Oct. 1947
