In the last months of World War Two, Nazi Germany tested an experimental fighter more spaceship than aircraft. Only now are we realising how inspired it was. BBC Future looks at the Horten Ho 229, one of aviation’s most futuristic designs.
In December, US aircraft maker Northrop Grumman unveiled a revolutionary design for a future fighter aircraft that could, theoretically, fly over the war zones of the coming century.
Their concept looks more like a flying saucer than a fighter plane – it is what aviation experts call a ‘flying wing’, a design which ditches the traditional tail fin at the back.
