|The term 'Foo Fighter' was used by Allied aircraft pilots in World War II to describe various UFOs or mysterious aerial phenomena seen in the skies over both the European and Pacific theaters of operations.|
Though "foo fighter" was named by the U.S. 415th Night Fighter Squadron, the term was also commonly used to mean any UFO sighting from that period.
|Formally reported from November 1944 onwards, witnesses often assumed that the foo fighters were secret weapons employed by the enemy. The Robertson Panel explored possible explanations, for instance that they were electrostatic phenomena similar to St. Elmo's fire, electromagnetic phenomena, or simply reflections of light from ice crystals.|
|The Horten Ho 229 – “Hitler’s Stealth fighter” was the first “flying wing” aircraft with a jet engine. It was the first plane with design elements, which can be referred to as stealth technology, to hinder the effectiveness of radar to detect the plane.|
In 1943, the head of the German Luftwaffe, Hermann Göring, presented what is known as the “3 X 1000” goal. Goring wanted a plane that could carry 1000 kg of bombs (2,200 lb), with a range of 1000 km (620 miles), at a speed of 1000 km/h (620 mph). Work on the next prototype version of the plane, the H.IX V3, ended when the American 3rd Army’s VII Corps on April 14, 1945 reached the Gotha plant in Friederichsroda.
|The only remaining Horten Ho 229 known was restored at the Steven F. Udvar-Hazy Center.|
The H.IX’s wings were made from two carbon injected plywood panels adhered to each other with a charcoal and sawdust mixture. Engineers at Northrop tested a non-flying reproduction and found the design gave about a 20 percent reduction in radar range detection over a conventional fighter of the day.
